This page is a product review and buyer's guide for swimming pool salt water systems - electronic chlorine generators / salt chlorine generators available to swimming pool owners. This page is a condensed list of some of the more popular brands that Swimming Pool Steve thinks you should consider if you want to upgrade your pool to have a salt water sanitizer system.
NOTE: I have the most current models of pool salt systems near the top of the page here but I have left the older and updated models of salt system below. These systems continue to need service and replacement cells for years to come so I have left this information up to help pool owners who have these salt systems.
So you want a salt water swimming pool? Great idea - pool owners love the convenience of using salt water and a chlorine generating cell to provide the sanitizer for
day to day use and maintenance of the pool. Salt water feels softer on the skin and is less irritating to skin, eyes, and bathing suits than traditional chlorine
treatments. All this stuff you have heard already but you may have also heard some other information which is less...true.
1) Salt water is NOT an alternative to chlorine. It IS chlorine but instead of buying chlorine you are "making" your own
2) Salt water pools are NOT maintenance free. They must be maintained just like any other form of chlorine or bromine pool
3) Salt water pools are NOT like ocean water. Ocean water has 10x the amount of salt of a salt water pool
4) Salt water CAN damage your swimming pool so you had better learn about galvanic corrosion!
This is a long form discussion from Swimming Pool Steve about salt water systems for swimming pools (electronic chlorine generators) and what you should know before you decide to buy one for your pool. Often with salt water pool technology there is a disconnect between what the system actually does and the pool owners expectation of function.
If you have decided that salt is right for your pool then the information below will help you to make an informed decision on which salt chlorine generator to buy. If you are on the fence and want more information about the potential concerns for your pool from salt water you can read this article about risks of salt water in pools. The information on this current page is an abbreviated salt system review which covers the most popular name brand systems on the market. If you would like you can also read the full (and updated) pool salt water system comparison article which details every brand, make and model of salt chlorinator available (not just the big 3 manufacturers).
How Do Salt Water Pools Work?
A salt water chlorine system for a swimming pool uses the base ingredient for chlorine, sodium chloride (table salt) and applies a small electrical voltage across two points in the water (inside the generation cell). This process causes the sodium molecule to separate from the chlorine molecule. The chlorine then becomes available to float around your pool looking for something to attach itself to. This is your "free chlorine" just like a traditional chlorine pool except that you "generated" your own chlorine instead of buying it directly in a concentrated form.
Since the salt level in your pool remains constant the process will repeat itself in that you can continue to create chlorine as you need it. The dial settings on your chlorine generator simply control how long the unit runs for before turning off. Every pool uses a unique amount of chlorine and you will need to learn what output settings are right to keep your pool in the range of 1-3ppm free chlorine at all times. This is what people are referring to when they say "maintenance free" which is obviously not correct since the pH, total alkalinity and calcium hardness levels are the bare minimum must also be maintained. It is worth noting that the type of chlorine that is generated from a salt water system has an extremely high pH. You will notice that with the addition of a salt water system to your pool that you will need to work to keep the pH down in the correct range.
At pH 8.2 and above the chlorine in your pool is over 90% inactive in the water so balancing your pH is very important
Does Salt Water Damage Swimming Pools?
In a word - yes. Anyone who tells you otherwise is selling you a salt water system or does not understand the electro-mechanical process of galvanic corrosion. This does not mean that you should avoid going with salt water. This simply means that you need to educate yourself about what this process is and more importantly what you can do as a pool owner to mitigate the damaging effects of galvanic corrosion.
To keep a long and technical subject brief, adding salt water to a pool causes tiny electrical charges to transfer between any metals that are in contact with the water. This includes steel walls in vinyl liner pools, rebar in concrete pools, aluminum, brass, steel, titanium are all examples of metals that exist in most pool installations. When exposed to salt water these metals will degrade at an advanced rate unless you do something to stop it.
The higher the salt level in the pool the greater the amount of current transferring between metal components in the pool. If the pool is not bonded this will allow for a greater "potential difference" or voltage in between these metal components which will further increase the rate at which current transfers between these metals. The current transfer process is what damages the metals so to protect against this your pool must be bonded and also have an outlet for any stray currents that do develop - namely a sacrificial anode.
Every swimming pool, and especially salt water swimming pools should have a sacrificial anode installed. The addition of this simple and low cost device will reduce dramatically the damage your pool experiences as a result of galvanic corrosion. While you may still experience localized anodization and oxidation of metals in your pool, especially those where two different metals are in direct contact, a sacrificial anode is the bare minimum level of protection that every pool needs. It is absolutely silly to not have one of these - plus they can easily be adapted to any existing system.
To help prevent localized problems you can, and should, add additional sacrificial anodes to your swimming pool. You can use stand alone zinc anodes that bolt directly to your ladder and other swimming pool rails, and you can get weighted zinc anodes that can sit inside the skimmer basket. For the relatively low cost of these items and the huge preventative protection against damage to integral components of your pool there is no question that every pool owner should be using all of these. The real question is why have you not been using them already? This is more than 30 year old technology that we are talking about so every pool technician working today should be able to explain why you need these - and many can not. As a pool owner you should take the initiative to learn about these subjects since it is your money on the line anyway!
How To Install A Sacrificial Anode For A Pool
Installing a sacrificial anode on your pool system is an easy do-it-yourself project. An inline anode can easily be installed on almost any pool system with the only question being which style to choose for the type of pipe that your pump and filter are plumbed in with. The picture of the anode above is designed to be drilled into a rigid or semi-rigid pipe and then it is clamped in place with a gasket and two pipe clamps.
More and more swimming pools are now plumbed with PVC, either rigid or flexible PVC. If this is what you have in the pump room then instead of drilling into the pipe you can also install a Tee style inline anode. Instead of drilling a hole in the pipe and inserting the anode, this is a standard PVC tee fitting that has been fitted with a zinc anode. While it requires you to cut open the pipe and remove an small section to accommodate the tee fitting, a primed and glued anode is better than a clamp and gasket style. If you have any other piping than PVC then the above pictured anode is the one you want.
Once the anode is installed be sure to attach it to the bonding grid with a large gauge bare copper wire. #6 is common in Canada, and #8 is common in the U.S. but refer to your local requirements for correct wire sizing.
How To Install A Salt Water System On A Pool
Installing a salt water system is a very easy process that pretty much any pool owner could do themselves. If you can cut out a piece of PVC and install the salt cell by priming and gluing the two connections - PRESTO - you have installed your own salt water generator. While there is a little more to know than that, cutting and gluing in the salt cell is about the extent of the technical aspect of the installation.
Flow meters - Salt systems have a flow switch which measures the flow of the water in order to prevent the cell from generating chlorine if there is no water flow. This is a very important safety issue. For this reason you should install the flow meter in a straight section of pipe. It should be 10x the pipe diameter in front of the flow meter and 4x the pipe diameter following the flow meter. For 2" pipe that would be 20" and 8" in a clear and straight run with no valves or elbow fittings. Some salt systems have a flow switch separate from the cell while others have the flow switch integrated into the cell itself.
Location - The salt water cell MUST be installed last in the line of equipment. Pump, filter, heater, cell, pool return is the order that the equipment should be installed in. If you were to install the salt cell before the heater you would be sending concentrated chlorine directly into your heater which would certainly ruin it in short order.
Check valve - Since the chlorine can travel backwards through your pool system on occasion, a chlorine resistant check valve (one way valve) should be installed in between the heater and the salt cell. This will prevent chlorine from tracking backwards through the system any time the pump turns off. Having the cell sloped downhill from the heater is not good enough as the chlorine can easily travel backwards in the system since it is a closed loop system. Since the check valve will be exposed to high levels of chlorine, a regular check valve is not ideal, Instead you should pay a little more and get a corrosion resistant check valve.
Adding salt - Choose a high quality swimming pool salt to avoid impurities in your pool. When it comes time to add salt to your pool you will need to know the total amount of salt your system requires to operate (typically 1500 - 4000ppm) but you also need to consider the current salt levels that you have. Since you have likely been using chlorine in your pool previously you will already have a salt level anywhere from a few hundred up to 1000ppm. Before you add the recommended amount of salt to your pool you should test your water and find out how much salt you already have. Salt test strips will give you a good enough reading to save you a trip to the local water lab. If you add too much salt the only way to reduce sodium level is to drain water from the pool and replace with fresh water. When you add the salt to your pool, allow for 24 hours before turning on the salt generator cell. During this first 24 hours brush down your pool multiple times to help the salt to dissolve.
Bad Things About Salt Water Pools
When you buy a salt water system for your pool it is important to understand how the system will work and what to expect in terms of how this will likely change the way in which your pool chemistry needs to be maintained. This is not a problem in and of itself but something you should be aware of if you intend to switch from traditional chlorine treatments to salt water chlorine. Swimming Pool Steve actually does endorse salt systems despite how many pool owners perceive feedback about the potential for problems with salt water - really you just need to know what you are getting. There are absolutely benefits to having a salt system for your pool - but also potential drawbacks.
Good Things About Salt Water Pools
Since there are definitely some downsides to installing a salt water system for your pool why would anyone want one? This video explains some of the most common reasons that pool owners love their salt water system. Every pool is unique and similarly each pool owner has a unique circumstance for what they are looking for from a salt water pool. What could be a great choice for one pool owner might fall flat for another. This video will help you to understand why salt water pools are so popular.
Salt Water System Reviews For Above Ground Pools
Hayward Aqua-Trol above ground pool chlorine generator
Buy from Amazon: Hayward AQ-TROL-RJ
Buy from Amazon.ca: Hayward AQ-TROL-RJ-CUL
For above ground and on-ground pools up to 18,000 gallons this system requires the generator cell to be mounted directly to the return line of the pool. This is different from inground pool salt water cells which are located in the pump room - for above ground pools the cell is remotely mounted to the pool wall at the return line. This unit does not require a hard-wired electrical connection for the control box, instead coming with a plug in cord end for use with an approved GFI receptacle. From a do-it-yourself perspective this system is extremely easy for the average pool owner to install and operate themselves. Hayward is one of the leading names in swimming pool equipment as well as salt water through their Goldline brand. If you want a high quality salt water system for your above ground pool this is one of your best options. The RJ Aqua Trolmodel mounts vertically under the return jet (RJ) of the pool. The HP Aqua Trol is for standard hose/pipe connections (HP). The HP model has an external flow switch similar to the inground versions which is why the HP model is slightly more money. The RJ has a flow switch also but it is built into the salt cell itself.
Pentair IC15 Above Ground Pool Salt Water Generator
Buy from Amazon: Pentair IC-15 Salt System (above ground pools)
Buy from Amazon.ca: Pentair IC-15 Salt System (above ground pools)
Pentair is typically regarded as offering the highest quality pool and spa equipment in the industry. While this is an arguable point, many experienced pool technicians would agree that Pentair pool equipment is of higher quality than other common popular brand names - usually for a higher price. If you are not sure which salt water system would be best for your permanent above ground pool consider what brand pump, filter and/or control panel you have. The Pentair IC15 system is designed for above ground pools up to 15,000 gallons and outputs up to .60 lbs of chlorine per day. Control interface, automatic salt level readings and troubleshooting diagnostics are all controlled through the cell itself as opposed to the Hayward Aqua Trol which offers these features from the wall mounted control box.
Other above ground pool salt water systems - There are many other options in the world of above ground pool salt water systems however as a swimming pool contractor I only offer professional level solutions to my clients (and my readers). There are many very entry level pool salt water systems available however I can not provide detailed review information since I have never used any of these. If you have a permanent above ground pool then go with the Hayward Aqua Trol shown above but if you have a temporary above ground pool and you want to see what salt water is all about there may be some options for you. The Intex Salt Water Complete System might be a good option for temporary above ground pools like those from department stores or hardware stores.
Salt Water Chlorine Systems For Inground Swimming Pools
With salt water systems each cell will have a finite amount of chlorine it can generate over a lifetime. Whether you make chlorine fast or slow the total amount any given cell can generate remains essentially the same. For this reason, replacement of salt cells is a significant consideration into the total cost of converting your pool to salt water. In this video Steve talks about how long you can expect a salt water cell to last in your pool and what you can do to get more life from yours.
Before you purchase a salt water chlorine generator for an inground pool you need to know a little bit about how these systems work, but more importantly, how they fail. A salt water cell has a lifespan of 3-5 years on average (which means that a few last 1-3 years and also 5-7 years). When the cell fails it will not just stop functioning but instead will experience a reduction of the amount of chlorine it is able to generate.In year 1 your salt water cell may make enough chlorine for your pool when the dial is set to 50% output. By year 3 to generate the same levels of chlorine you might need to have the dial set to 70% - 80% output. At some point the failure will be that you keep your system set to 100% and it still can not meet the chlorine demands of your pool. At this time you would need to replace the cell.
As a pool professional I prefer to slightly oversize the salt cell for the pool. This allows to meet the chlorine demands with the cell now with low range settings (like 20%-30%) and when the cell begins to output less when it nears the end of its service life you can dial up the output. This can get you another season or two even out of your cell before requiring replacement.

New Salt Systems From Hayward
Hayward has recently released a new salt chlorine generation system to the pool market which is the S3 Omni system. Omni is the name of the automation line that Hayward uses and this move to the S3 Omni system is certainly to bring the salt systems under the Omni automation panel umbrella. Previously the AQR salt systems were almost original to the Goldline design at the time Hayward purchased the Goldline brand - the global leaders in pool salt systems at the time. This new S3 Omni update to the Hayward salt chlorine generation systems is a big step as the AQR models (still available on the open market product line) were some of the best salt chlorine systems available anywhere. For more information you can take a look on the Hayward website for New Hayward Salt Systems.

Salt chlorine generators are one of the most requested and sought after products in the swimming pool industry - barre none! I have written extensively about these systems and the potential for damage from salt water like this page about getting informed about salt water and in these articles I do speak poorly about the potential for damage from salt. I do think it warrants mentioning. However, it is also worth mentioning that many (most of) the potential downsides to salt water systems can be avoided with proper water chemistry maintenance in your pool. It is not the salt directly so much as the mismanagement of water chemistry which can lead to long term problems relating to salt water based on my experiences. In general I do endorse salt systems for pool owners who have a keen interest in this technology and a desire to have a salt water pool.
Updated Or Less Common Pool Salt System Info
Other model information for pool salt water systems - Below this section includes information about older, outdated, less-common and discontinued models of swimming pool salt water systems. Many of these systems are still viable options and available for sale however I endorse them less commonly than the systems higher up near the top of this page. Many of these systems will continue for years since many pool owners own these so information archives like this can still be useful. In addition to some of these older models being still available, the replacement salt cells are available for almost all of them either from the manufacturer directly or aftermarket / generic brand models.
Jandy AquaPure Ei
Buy from Local Jandy Dealer: APURE35
Buy from Amazon: Electrode Cell
Replacement Cell: R0511400
Buy from PoolSuppliesCanada.ca: Electrode Cell
Replacement Cell: R0511400
The Jandy AquaPure Ei is a stand-alone model that was offered by Jandy but was discontinued. Replacement cells and replacement parts are still available online and from your local pool stores. It is suitable for inground pools up to 35,000 gallons. This is a very compact unit so if space is an issue for you this would be a good system to consider. The main benefit of this unit is the easy installation intended for pool owners to be able to do themselves. This compact model has a daily chlorine output of up to 0.93 lbs and a lifetime output of 388 lbs of chlorine and the salt range is 3000-6000 ppm with 4000-4500 parts per million being ideal. Able to be powered with either 120V plug or 240V hardwire (plug in style units have a PLG part number).
In 2007 Jandy Pool Products was combined with the marine division of the Zodiac Group and formed the Zodiac Marine & Pool division which later became Zodiac Pool Systems, Inc. While Zodiac and Jandy are now under one ownership group, Fluidra, each still maintains a certain degree of individual product lines. The advantage in doing so is similar to how Pentair and Sta-Rite are the same company but operate individual product lines - it helps to increase market share where there are dense concentrations of pool dealers and retail stores. Competing stores often prefer to carry different product lines to prevent from having a price war between dealers in the same area.
Zodiac Salt Water Systems
Since Jandy and Zodiac had some independent lines of salt water systems I have separated these two however it should be noted that both are the same parent company now. Zodiac in particular offered a few different salt water chlorinator options and most of their systems operate at a notably higher salt level than other major brands. Since there is a linear increase in galvanic activity as the salt content of the pool increases this means a system designed to run at 4000 parts per million would have approximately 20% to 25% more potential for damaging galvanic activity. Every salt water pool should be bonded, including the equipment, and should have a sacrificial anode installed on the plumbing system. With a Zodiac salt water chlorinator it is even more important to do this than with other salt water systems.
Zodiac LM2-15

Buy from Amazon: FSOFT700
Replacement Cells: W28000
The Nature2 Fusion Soft 700 is part of a newer generation of salt systems from Fluidra for inground pools up to 12,000 gallons. These systems, based on the discontinued Zodiac DuoClear systems, combine a mineral pack along with a chlorine generation cell. The mineral pack is copper and colloidal silver and works to reduce chlorine demand as the silver is a bactericide and copper is an algaecide. This Fusion Soft system uses either the DuoClear 25 or Nature2 Fusion 25 replacement cartridges. The FSOFT700 has a daily maximum chlorine output of 0.625 lbs with a cartridge lifetime total of 260 lbs or chlorine generated with a recommended salt level of 3000 parts per million. This system can be powered by either the Nature2 Fusion Soft Power Pack (FUSIONM) or the AquaPure Power Center (APUREM) which are sold separately.
Nature2 Fusion Soft FSOFT1400

Buy from Amazon: FSOFT1400
Replacement Cartridge: W28002
Buy from PoolSuppliesCanada.ca: FSOFT1400
Replacement Cartridge: R0503000
The Nature2 Fusion Soft 1400 is the larger of the two Fusion Soft systems made for inground pools up to 40,000 gallons. These units are unique as they are designed to be ground mounted as opposed to most salt cells which are suspended in the plumbing system. The FSOFT1400 has a maximum 24 hour chlorine output of 1.25 lbs and a lifetime total of 520 lbs of chlorine generated with a salt range of 3000 ppm. It combines salt chlorination with natural minerals to clean and sanitize the pool water. While the mineral pack (copper and silver) systems do help to reduce chlorine demand there is some concern for adding metals to the pool water. If you want to see why having metals in your water can be bad you could ask the Olympic Committee that was in charge of the swimming pools at the Rio Olympics. This Fusion Soft system uses either the DuoClear 45 or Nature2 Fusion 45 replacement cartridges. This unit requires a power pack to function and can be paired with either the Nature2 Fusion Power Pack (FUSIONM) or the AquaRite Power Center (APUREM) which can be wired for either 120 or 240 volts.
Nature2 Fusion Power Pack
Buy from Local Jandy Dealer: FUSIONM
Buy from Amazon: FUSIONM
Buy from PoolSuppliesCanada.ca: FUSIONM
The Nature2 Fusion Power Pack is a heavy-duty stainless steel power center used with the Fusion Soft Cell Kit to control chlorine generation and mineral dispersion. The digital display shows salt, temperature, flow rate and status. This power unit can be paired with AquaLink automation systems for easy control from your smart phone or smart device. It can wired for 120V or 240V and connects to the pool pump so it is only on when the pump is on.
Zodiac salt water systems have undergone many changes, model redesigns and upgrades over the years along with joining with the Jandy Pool Products line. With two complete lines of salt water systems now, from Jandy and Zodiac, they have been working to merge the technologies of these systems. The only Zodiac salt systems not shown on this list are the DuoClear systems. The DuoClear units have been rebranded into the Fusion series. If you have an existing DuoClear system and need to find replacement cells then the three models of DuoClear replacement cells are the DuoClear 25 Cell, the DuoClear 35 Cell and the DuoClear 45 Cell.
AutoPilot Salt Water Systems
AquaCal AutoPilot Inc. has been offering salt water chlorine systems for swimming pools since 1976 and they are based in the USA. They advertise that they have sold
over 500,000 salt chlorinator units and do not show any serious signs for concern with the BBB in terms of product or warranty support. In some areas of North America
there is very little market penetration for AutoPilot, where in other areas AutoPilot systems are one of the most common brands you will see working in the field.
AutoPilot Pool Pilot DIG35
Buy from Amazon: DIG-35
Replacement Manifold: PPM1
Replacement Cell: PPC1
This is the complete Pool Pilot Digital DIG-35 Salt Chlorine Generator system for swimming pools up to 40,000 gallons. The system pictured includes the Pool Pilot Digital power supply, the PPM1 patented bypass manifold and the PPC1 salt cell. This unit comes wired for 220 volt electrical service but can be converted to 110 volt power supply. A complete Pool Pilot Digital Salt Chlorine Generating system can use one of the other sized salt manifolds and cells available to compliment the size of your swimming pool - PPC1, PPC3, PPC4, PPC5 (listed below). This model is compatible with the AutoPilot Pool Pilot RC-35/22 replacement cells, now called PPC1 salt cells. It should be noted that the manufacturer recommends replacing the salt cell cord when you replace the salt cell.
AutoPilot Bypass Manifold PPM1
Buy from Amazon: PPM1
Replacement Cell: PPC1
These patented bypass manifolds from AutoPilot are preassembled units made to regulate water flow through the salt cell. They have a built-in three-way sensor device, spring check valve, inline strainer and replaceable salt cell. The PPC1 salt cell procudes a lifetime total of 200 lbs of chlorine and up to 1.28 lbs of chlorine generated per 24 hours with a salt range of 3000-3500 ppm. It makes up part of the complete system and requires a power supply to function. This PPM1 manifold can be paired with Pool Pilot Digital, Pool Pilot Total Control power supply (product #75003) or the Pool Pilot Soft Touch to be used on pools up to 40,000 gallons. For smaller pools up to 28,000 gallons, the PPM1 manifold can be paired with the Pool Pilot Digital Nano power supply. The PPC1 replaces salt cell models RC-35/22, SC-36, R-5, and A-150 (these can still be found online and in stores).
AutoPilot Bypass Manifold PPM3
Buy from Amazon: PPM3
Replacement Cell: PPC3
The next step up in the Pool Pilot Digital family is the PPM3 (previously RC-42) which is suitable for pools up to 42,000 gallons in size. Like the other bypass manifolds this has the spring check valve, an inline debris filter and the Tri-Sensor which monitors water flow, temperature and salt level. It also needs to be paired with a power source to work. The PPC3 salt cell that is included on this model produces 1.56 lbs of chlorine in 24 hours with a total lifetime output of 300 lbs of chlorine generated with a salt range of 3000 to 3500 parts per million. The PPC3 salt cell replaces models RC-42, SC-48, RC-7 and AP-250 (these should still be available online and in your local pool store).
AutoPilot Bypass Manifold PPM4
Buy from Amazon: PPM4
Replacement Cell: PPC4
The PPM4 is the second largest salt system from the Pool Pilot Digital series and is capable of sanitizing swimming pools up to 52,000 gallons in size. It has a 24 hour maximum chlorine output of 1.92 lbs and a lifetime output of 575 lbs with a salt range of 3000 to 3500 parts per million. It has all the features listed under the PPM1 and PPM3 and also needs an external power supply. The salt cell cord is recommended to be replaced whenever the salt cell is replaced. The PPC4 salt cell is the newer model that replaces the RC-52 and SC-60.
AutoPilot Bypass Manifold PPM5
Buy from Amazon: PPM5
Replacement Cell: CC-15
This PPM5, previously the Pool Pilot Digital CC-15, is the largest salt system in the Pool Pilot Digital line used for large residential pools or commercial pools up to 80,000 gallons. This model has an extremely high output cell that can generate as much chlorine as almost any other system available on the residential market. The maximum 24 hour chlorine output level is 2.5 lbs and the lifetime total is 1000 lbs with a salt range of 3000 to 3500 parts per million. This also needs to be paired with the external power supply to function. The PPC5 salt cell replaces cell models CC-15, RC-15 and AP-500.
Pool Pilot DIG220 Digitial Power Supply
Buy from Amazon: DIG220
The Pool Pilot DIG220 powers and completes the salt chlorine generating system when paired with the PPM1, PPM3, PPM4 or PPM5 manifold and base. It has a digital display that shows water temperature, salt level, production level, cleaning and boos cycles, and will even tell you how much salt to add if your pool runs low. This power center has an optional relay switch for an internal time clock to control the pool pump. In order to use this feature an additional part is required which is a relay & wiring harness with part number APK0004. This unit has a temperature compensation feature that will adjust the production of chlorine based on the temperature of the pool and will operate up to 104 degrees Fahrenheit. The DIG220 can sanitize pools up to 80,000 gallons and is able to produce up to 2.62 lbs of chlorine per day depending on the size of the salt cell. Easily upgraded to work with the CoPilot Ozonator for additional sanitization. It comes standard wired for 220 volts but can be converted to 110 volts if needed.
Pool Pilot Digital Nano DN2
Buy from Amazon: DN2
Replacement Cell: PCC2 (previously RC-28)
This is the Pool Pilot Digital Nano complete salt chlorine generating system. This unit was made for pools up to 28,000 gallons and is wired for 220 volt electrical service but can be converted to 110 volts if needed. It comes with the PPC2 salt cell, previously the RC-28, that produces a maximum of 1.06 lbs of chlorine in 24 hours and about 300 lbs in the lifespan of a cell with a salt range of 2500-3500 parts per million. The Digital Nano is still available as two separate units, the DN1 which is wired for 110V and the DN2 which is wired for 220V but now the DN2 is the most sold unit of the two with the ability to convert power requirements. The Pool Pilot Digital Nano power center can also power the PPM1 bypass manifold listed above.
Pool Pilot Digital Nano Plus DNP2
Buy from Amazon: DNP2
Replacement Cell: PCC2
The Pool Pilot Digital Nano Plus DNP2 is a dual voltage system (wired for 220V but can be converted to 110V) which is intended for use on pools up to 32,000 gallons. The DNP2 comes with the PP2 salt cell, previously RC-28, that has a maximum daily chlorine output of 1.06 lbs and lifetime total of 300 lbs of chlorine generated with a salt range of 2500-3500 ppm. This unit is available still in two different models, DNP1 wired for 110V and DNP2 wired for 220V. However, the company has upgraded the power supply to be standard wired for 220 volts but able to be converted to 110 volts without having to choose between the two models. The Digital Nano Plus can also supply power for the PPM1 manifold listed above.
Pool Pilot Soft Touch Power Supply
Buy from Amazon: ST-220
The Pool Pilot Soft Touch power supply is designed to offer similar functions to the flagship Pool Pilot Digital system in a slightly more cost effective unit. The Soft Touch has a more basic visual display than the Pool Pilot Digital but most importantly it does not have the internal clock and ability to control the pump operation through a relay like the Digital systems do. Often the power unit is sold separately from the manifold with salt cell so be sure that you are purchasing the correct item you are looking for. This power supply can be paired with the PPM1, PPM3, PPM4 and PPM5 bypass manifolds listed above.
Pool Pilot Digital is the flagship product in the Pool Pilot lineup. The main feature advantage of the Pool Pilot Digital system is the internal time clock that allows you to control the operation of your pool pump. In order to use this feature an additional part is required which is a relay & wiring harness with part number APK0004. Most of the Pool Pilot lines from AutoPilot have a very large range of salt that the system is able to operate in. While the system may be programmed to continue to function at elevated salt levels, the reality is that salt levels above 4000 ppm are not advised. Salt levels up to sea water salt levels as the Pool Pilot advertises would certainly be something you want to avoid. If you were to have salt levels at 10,000 to 30,000 ppm you can bet that there will be some seriously advanced decay and corrosion happening in your pool.
Intex Salt Water Systems
Intex is a very popular brand if for no other reason than being the least expensive salt chlorination system on the residential market. Intex has traditionally been
involved in the aboveground pool market where Intex pools hold a large market share in North America. While the quality of an Intex system may not be as high as more
expensive name brand units, if you have a very inexpensive aboveground pool the price point for an Intex system might be the only salt chlorinator that is within your
budget. With reasonable expectations of performance and longevity the Intex systems can deliver adequate performance on a minimal budget.
Intex Krystal Clear Saltwater System
Buy from Amazon: 26667EG
The Intex Krystal Clear Salt Water System With E.C.O (Electro Catalytic Oxidation) comes in a few different sizes. This is the smallest of the Intex systems which is suitable for aboveground pools up to 7000 gallons. The ECO system is newer, previously being a copper ionizer, but problems with the copper-based system led to the new ECO oxidizing models. It has been redesigned into a more compact unit (old model #28667EG). This sized system is suitable for above ground pools up to 7,000 gallons and is powered by 110/120 volts. The maximum 24 hour chlorine output is 0.27 lbs with a salt range of 3000 ppm. The Titanium electrode is what will need replacing and this model uses the 11899 Cell or 11900 ECO Cell. These are not super common online but you can order them directly from Intex or from your local pool store.
Intex Krystal Clear Deluxe Saltwater System
Buy from Amazon: 26669EG
This Intex Krystal Clear Deluxe Salt Water System With E.C.O. is slightly larger and intended for pools up to 15,000 gallons and requires 120V power supply. All of the E.C.O. systems (electrocatalytic oxidation) combine salt water electrolysis for generating chlorine as well as a separate system for creating hydroxyl radicals. The hydroxyl radicals are highly active oxidizers and work to reduce chlorine demand. This unit was also redesigned into a more compact unit (old model #28669EG). The Deluxe system generates up to 0.63 lbs of chlorine in 24 hours with a 3000 parts per million salt range. The replacement electrodes are the 11904 Cell or the 11905 ECO Cell.
The Intex Krystal Clear Salt Water & Ozone System
Buy from Amazon: 26665EG
The Intex Krystal Clear Salt Water & Ozone System combines chlorine derived from salt water with an ozone generator for a system that provides water clarity with minimal chlorine for above ground pools up to 15,000 gallons. This is also a newer model designed for more compact spaces (old model #28665EG). Intex prefers to combine technologies with a discontinued copper ionizer system along with the E.C.O. system or this ozone system. The actual function of the E.C.O. and this system would be very similar in that both oxidize the water as well as chlorinate it. This model from Intex generates 0.58 lbs of chlorine in 24 hours with a salt range of 3000 ppm. It also generates 150 mg of ozone output per hour, equal to about 3600 mg, or 0.12 oz, per 24 hours. It uses the 11374 Titanium replacement electrode and the electrical requirement is 120V for this system for function.
When you buy an Intex salt water system you need to understand that you are buying the cheapest salt system on the market. It will, under the most ideal of circumstances, operate for a few years. The quality of materials used for the Intex systems cannot compare to much more expensive salt water systems. The information made available from Intex as to the longevity of their products as well as information about the technology used (such as with E.C.O.) is difficult to come by. Much of the success of the Intex line is the cleverly worded marketing combined with the rock bottom price point, however if you are looking for a salt water system, any salt water system that you can afford, then this is a good entry level product line to get your feet wet with.
Many older models of Intex salt water systems are still available through retailers such as Ebay and Amazon.com. The older models of the CS7110 and the CS8110 included a copper ionizer that helped to reduce chlorine demand by adding ionized copper to the water which acts as a algaecide. Improper maintenance of pools with copper in the water can easily result in staining of the pool. Copper is also responsible for turning light colored hair green and having a copper injection system on an entry level above ground pool system is not ideal. The problem is not that the technology does not work, but more that the likelihood of having improperly balanced water in a cheap above ground pool is statistically much higher than with any other kind of pool. I would suspect that Intex dealt with many angry customers with green hair before they decided to update the product line and replace this feature with a high output oxidizing E.C.O. system. If you have found a good deal on an older model of Intex salt system that has the copper ionizer you can still successfully use this system in your pool. You can learn about and monitor your copper levels or you can also disconnect the copper ionizer and operate the system on the salt chlorine generator exclusively. Intex also makes full combination pool systems that include a small pump and filter in addition to the salt water and E.C.O. system. These combination units come in two different sizes: The Intex pump, filter & salt water up to 8,500 gallons and the Intex pump, filter & salt water up to 15,000 gallons. If you are looking for a complete all-in-one filtration and sanitizing system for your above ground pool then this would be a very cost effective choice.
CircuPool Salt Water Systems
CircuPool was once part of the CompuPool brand but as of 2013 CircuPool is no longer affiliated with CompuPool. CircuPool has taken a much stronger stance on customer service and product support than CompuPool which is probably why CompuPool carries a very low BBB rating (F) largely to do with warranty related problems. Being that the product is manufactured in Australia it is reasonable to assume that this would account for some of
the negative experiences that customers have had since support and replacement parts might be far away.
CircuPool itself has been around since 1997 so while they are not as established as brands such as Pentair or Hayward, they are not a brand new company that you should
worry about going away before your warranty expires. The newest products from CircuPool all advertise that they are manufactured in the USA.
CircuPool SJ-20
Buy from Amazon: SJ-20
The CircuPool SJ-20 is a salt system capable of sanitizing inground pools up to 20,000 gallons. The SJ series from CircuPool is designed as a more basic version of the RJ series with a similar designed function but somewhat more limited interface and display. It has a maximum 24 hour chlorine output of 0.87 lbs and a lifetime total of 362 lbs with a salt range of 3,500 ppm. It uses the SJ-20 replacement cell. This unit comes wired for 240 volts but can be converted to 120 volts if needed.
CircuPool SJ-35
Buy from Amazon: SJ-40
The CircuPool SJ-40 is the next size up in the SJ series and is suitable for inground pools up to 40,000 gallons in size. This unit features heavy-duty construction and LED display lights. It generates up to 1.6 lbs of chlorine in 24 hours with a lifetime total of 700 lbs of chlorine generated and a salt range of 3,000 parts per million. The Titanium cell gets replaced when needed with the SJ-40RC. The CircuPool SJ series come standard wired at 240V but can be converted to 120V moving the internal jumpers.
CircuPool SJ-55
Buy from Amazon: SJ-55
The next size up is the CircuPool SJ-55 salt system which is suitable for inground pools up to 55,000 gallons. If you are looking for a lower cost unit with a strong warranty but you have a very large pool then this should be one of the systems that you consider. Like the other models in the SJ series, this is a dual voltage unit. It generates up to 2.3 lbs of chlorine per day with a lifetime total of 975 lbs produced. The replacement cell for this size unit is the SJ-55RC. Salinity range is stated as 3,000+ parts per million.
CircuPool has a number of additional salt systems both current and archived. The CircuPool RJ series has had three redesigns and is the flagship salt system from CircuPool. The SJ series offer the same functionality as the RJ series with a few less frills such as the lack of a display screen in lieu of light indicators. This means reduced ability to diagnose and interact with the system but the chlorine production is all you need if you are looking for the most cost effective option.
The previous generations of CircuPool included the SI series as well as the SI + (SI plus) series which had an extra long life cell. Both of these lines have been dropped in place of the newer RJ series though the Universal40 system appears to be identical to the older SI45 system. If you would like to see more options from the RJ and RJ Extended Life series you can view them on the CircuPool website.
One of the areas that really makes CircuPool stand out is in their unique warranty offerings. While their warranty sounds very impressive it is actually very comparable to other brands in that it is pro rated to cover only part of the cell replacement costs depending on how far into the warranty period you are. Also the unique way they phrase their warranty period would make it seem their warranty is much longer when it is much closer than that. Companies like Hayward and Pentair have recently been introducing limited, or no warranty, for pool equipment that is installed by the pool owner (not a professional pool company) or bought online. CircuPool has taken advantage of this limitation from other manufacturers and advertises heavily that DIY installation of their systems will not have any effect on their warranty coverage.
Solaxx Salt Water Systems
Solaxx has been in the pool and spa industry for over 30 years and they advertise that over 100,000 customers are using their products. While decidedly smaller than
some of the bigger names, Solaxx has been around for a while. Solaxx is based in Florida and they deal primarily in ozone, UV and salt water systems as well as water
testing equipment.
Solaxx Saltron Retro
Buy from Amazon: Retro
Replacement Cell: CLG10A-010
The Solaxx Saltron Retro is designed to meet the needs of pool owners looking for easy installation - no plumbing required. These salt water systems are unique in that the chlorine generation cell hangs in the pool water from the edge of the pool. These systems are suitable for either inground or aboveground pools up to 20,000 gallons. It generates up to 0.4 lbs of chlorine per day with a lifetime total of 166 lbs and a salt range of 3000-4000 ppm. Can be used at either 115V or 230V.
Solaxx Saltron Reliant CLG225A
Buy from Amazon: CLG225A
The Saltron Reliant CLG225A is made for pools up to 25,000 gallons and is the middle sized system of the three Saltron Reliant series offered by Solaxx. This model generates 1.15 lbs of chlorine in a 24 hour period with a lifetime total of 480 lbs and can perform in salt range of 500-6000 ppm. The CLG225A Cell can be found both online and through your local pool store. This unit has an open power range so it works at 120 V or 240 V.
Solaxx Saltron Reliant CLG240A
Buy from Amazon: CLG240A
The Saltron Reliant CLG240A is the largest of the Saltron Reliant line. This system is rated for inground pools up to 40,000 gallons and has chlorine production levels that are on par with some of the biggest name brands in the industry. It generates a 24 hour maximum of 1.65 lbs of chlorine with a lifetime output of 688 lbs. This model uses CLG240A replacement cell. The same electrical requirements and description apply to this model as the others in this series; 120-240 volts. The Reliant series is made for simplicity with the smallest number of switching parts and easy operation.
Solaxx has a number of other products in the pool and spa industry most of which are salt water chlorinators, ozone systems and UV systems. They offer a salt chlorinator system combined with an ozone system in the Solaxx Salt3 Integrated Salt Ozone System. Pairing multiple layers of sanitization is the best way to maximize clean pool water.
Best Salt Water Pool Systems
Pool size - The volume of pool that each potential salt system can handle has been taken from each manufacturer directly. This means that you need to factor in that most companies are probably advertising the absolute best case, ideal operating conditions. It is only natural that each marketing team would try to make their own systems sound the best. This is why you can not simply look at the volume recommendation to determine which salt system you should get. If a system is rated to 40,000 gallons, and you have a 40,000 gallon pool, logic would dictate that this system would work on your pool...but that is not the case. Right away you should be deducting a minimum of 25% off of the volume capacity of the system. This would account for anything other than ideal conditions. Rain, poor water chemistry, debris in the pool, heavy bather loads, dirty filters and the presence of nitrates or phosphates all will reduce how much volume the system can sanitize in a real world setting. Further to this, as a general rule of thumb, you are always supposed to oversize your salt system as this will have a great effect on the longevity of the cell. The longer your cell needs to operate for to keep up with your chlorine needs, the sooner you will need to replace it. With an oversized system you can operate it on a very low setting to meet your needs and then begin to increase your output setting over time as the cell begins to produce less and less chlorine. You are further ahead to way oversize the system as opposed to have it undersized by even a small amount.
Chlorine maximum output - This is one of the most important factors that you should be looking at with each salt system you consider however the information is not as straight forward as it would seem. The chlorine output and maximum yield over the cell lifespan values need to be taken with a grain of salt. There are many variables that affect these numbers. The maximum hourly output value for each system is a more reliable statistic to look at as each of these values have been collected from each individual manufacturer and are factually accurate. The lifetime chlorine output however is not a reliable statistic. Some manufacturers provide clear information about how many hours that their cell will last (should last). Some manufacturers provide how many ampere-hours the cell will last (should last), and some manufacturers do not publish this data at all. There is a lot of important information to be garnered from this. The hours of operation rating provided by manufacturers is the most clear statistic however very few systems make this information available. The ampere-hour (amp hour) rating is a tricky way that some systems are marketed being that it would be easy to mistake this for a comparison to hours of operation. The two are not the same. If a salt system operated at 4 amps when at full power, and had an ampere-hour rating of 10,000 then this sounds like you can expect to operate your system for at least 10,000 hours. In actuality, this would mean that 10,000 divided by 4 is how long you could expect your cell to operate, or 2500 hours of operation. In many cases the data from the manufacturers had to be extrapolated in order to provide a working number for comparison of expected total lifespan. PLEASE NOTE that even understanding that the total lifespan of the cell is a calculated value, you need to be careful to not weigh this one statistic too heavily in your decision. The daily chlorine output of the system does give you a good idea of the capability of the cell but the total lifespan of the cell is based on manufacturers ideal estimation and NOT real world settings.
Salt range - All salt systems have a range of salinity that they operate at. Some systems stop functioning when the values fall outside of the normal range where others continue to operate with reduced functionality. For each system the ideal salt value recommended by the manufacturer has been provided. Many of the systems here boast a huge range that they can operate at with some as much as 1000ppm up to 30,000 ppm. The first thing that you need to know about salt content is that less is more. The lower the salt level in your pool the lower the rate of galvanic activity (and damage) to your pool as discussed in this article: Is salt water bad for your pool? Around 3000 to 3500 is the maximum level of salt that you should use. At salt levels higher than this the rate of galvanic corrosion can be problematic. Use of a sacrificial anode, as well as being sure that your pool is bonded, are both ways you can (should) help your pool to protect itself against damage from salt water. While some salt systems advertise being able to operate up to 30,000 ppm of salt this is not something that you would ever want to do to your pool. Salt levels like this, as found in ocean water, is far too damaging for regular swimming pools and almost all pool equipment is "not rated for salt water" when you read the fine print. In this wording, manufacturers are not talking about salt water systems at 3000 ppm, they are talking about salt water like in the ocean at 30,000 ppm.
Salt Water System Warranty
One of the most important details that you need to consider about your new salt system is what kind of warranty you will get with it. The warranty for salt chlorine
generators is usually confusing and commonly less inclusive than you would hope it to be. First, almost all manufacturers offer a pro rated warranty which means that
the older your cell is, the less percentage of the replacement price they will cover should it fail before the warranty period ends. Salt cell deterioration is
considered to be normal wear and tear and is not usually covered unless there is some kind of failure of the system. If you have a high chlorine demand and you run
your salt cell around the clock to keep up then you can expect that it will fail before the warranty period expires. If the system indicates more operational hours
(or ampere-hours) than what is covered under warranty then you are out of luck since this is just normal operation.
Some manufacturers (many) are now encouraging pool owners to buy from local brick and mortar retail stores, as well as with pool dealers, by altering (or voiding) the
warranty of the system unless it is installed by a professional (and you can prove this with a receipt). While the logic is better for things like pool pumps or heaters which can be technically challenging to install, the
reality is that a salt system is easy to install and any pool owner could likely do a fine job of it with little instruction. If you plan to install the system
yourself then you need to be aware of how this will affect your warranty coverage. Also, what constitutes a professional installation? Since pool guys are not a
recognized trade in most areas of North America then this means a receipt for a pool company, plumber, electrician or contractor. Some manufacturers will approve self
installation if you are a qualified trade professional in a relatable trade. The warranty terms, period, and coverage limitations are different with every
manufacturer. If you want to be 100% certain about your warranty coverage then the best option is to call the manufacturer directly and find out about their
installation requirements, pro rated warranty and how they handle warranty procedures in your area.
