The CircuPool RJ20 PLUS is an electronic saltwater chlorine generator with advanced, third-generation salt pool technology. RJ PLUS models feature electrolytic titanium cells with rare-earth minerals, providing an extended-lifespan cell (as much as 50% longer than other leading brands).
This chlorinator works with all existing pump and filtration systems to reliably supply the swimming pool with pure chlorine every single day! The RJ20 PLUS has a 20,000 gallons max capacity. The RJ PLUS series uses low salt levels and helps create a silky soft feeling in the pool water, for the ultimate swimming experience.
The complete RJ PLUS salt system from CircuPool features three main components: the Control Module, the Electrolytic Cell, and the Flow Switch, along with the usual miscellaneous hardware and documentation for install.
The RJ-PLUS Series will replace Hayward® Aqua Rite® systems with no cutting or gluing, making it a snap to upgrade your salt pool system!
Features:
- Titanium Cell with industry-leading 7-Year Limited Warranty.
- RJ cells feature CellSaver™ technology for Variable-Speed Pumps, helping to extend its operation lifespan when used in combination with VS pumps which provide longer than average run times.
- 3rd-Generation system, combining the best in advanced technology with a reliable and proven track record.
- Cell has industry-leading lifespan (as much as 50% longer lasting). Longer cell-life means even greater savings over the years.
- CircuPool products are backed by USA-Based Expert Support & USA-Based Factory Warranty

General FAQ
These saltwater chlorine generator systems come with everything you need except salt, PVC glue, primer, a saw, and a few common tools.
In addition to adding salt to your pool water, installation entails adding one new piece of equipment to your pool. This can be performed by a handyman, plumber, electrician, pool contractor or Do-It-Yourself (DIY).
If you are contemplating installation, read more here.
The simple, industry-wide, rule-of-thumb is that your salt system should be sized at 1.5 times your pool size, or more, for the temperate and colder parts of the US.
If you live in the southern sunbelt, then you should select a system with specs of at least 2 times your pool size.
Bear in mind that an undersized system will be a constant challenge, at best, while an oversized system will extend cell life and give you reserve capacity for weather events and periods of heavy use.
To find out more, click here.
Your CircuPool RJ-PLUS series salt chlorinator operates under a “duty cycle” by which partial output is achieved by periods of 100% output and periods of standby operation to achieve the partial output.
Temporarily turn the unit up to “Power Max” and after several minutes of operation, check for amperage and instantaneous salinity readings before turning it back to the original setting.
If you still had 0 amps and no salinity reading, then call our Technical Support team at (866) 766-5243 for further assistance.
The fuse reset button may have tripped. This is the Control Module's built-in circuit breaker located on the bottom of the Control Module (CM) between the two cables in the aluminum base.
If the button clicks, then check whether the CM will turn on.
Next, the fuse may have blown and needs to be replaced. The fuse is located inside the CM on the upper right-hand side of the main power circuit board. The 15 AMP fuse is available at any electronics or auto parts store.
If the new fuse blows, then disconnect the salt cell and try another fuse to determine if the CM or the Cell is causing the fuses to blow.
At this point, call our Technical Support team and they can assist you the rest of the way.
review
Received the system three days after ordering. Arrived in good condition, good packaging, encased in shaped protective foam and well protected. Instructions and documentation were clear and simple to understand. Only needed my hacksaw, pvc primer, pvc glue, drill, and screwdriver to install the complete system, which took about an hour and fifteen minutes for me. I added the salt to my pool the day I ordered it, so the system was ready to run when I installed it. Ran it on SuperCL mode for 24 hours, and the chlorine was high in the morning. Run it now at 55% for 8 hours a day and it seems to be keeping up. No leaks, no warning lights, seems like its going to be good.

RJ-30 works great
I bought the RJ-30 (upgrade from the RJ-20 which would have been fine). Installed it myself, but I have some mechanical and electrical experience. Cutting and glueing pipes isn't that difficult, but you want to measure 2-3 times, and cut once... and so forth. Electrical wiring isn't everybody's thing, but it's not complicated either. But be careful if you do it yourself as you'll be dealing with 110/220V. Setting up my water was surprisingly more effort than expected. I thought our water chemicals were OK , but after getting all the chemical indicators tested at the store, we found a very high level of Phosphate (food for algae), and our level of Stabilizer was too low, making the Chlorine in the pool disappear rapidly. So, make the effort to do this right, you may learn something. After fixing that (took >1 week to have it all good), we finally started the system. Over the following couple of weeks we dialed in Chlorine production (e.g., we started at 65%, but that turned out too high). It takes a while for a pool to find its balance. So, keep checking for a weeks! I have had the system running now (Northern CA) for about a month. The RJ-30 operates my 15k gallon pool just fine, currently at a 50% setting. We're very happy with the water quality overall, and finally don't have to worry about coming back from a trip and find the pool in bad shape. Still need to check ph-value regularly, just like before. The system works with our 2-speed pump, it produces Chlorine at both speeds. Overall, the cell and other hardware seems to be of good quality, including the controller unit. I expect this to be a good solution in the long run, but time will tell. Until then, I recommend this.

Questions From Customers
Q:
what is the difference between SJ & the RJ systems?
Asked by: Bill
- 3/6/2017
A: Great question. Beside the main differences in power and lifespan, here are a few of the things that set them apart once they are in your hands:
The SJ models are very simple, easy-to-use systems. They have status lights that verify the unit is working, tell you at what power level it is set, and whether you need to clean the cell or add salt to the pool. Because it is simple there is less to think about, it is particularly low maintenance (no acid is required to clean the cell), and it is also less expensive.
The RJ and RJ+ models are the flagship systems. They are more powerful and longer lasting. They have a digital screen and touch keypad, giving you more control and diagnostics. It displays the salinity level in real time, calculates the running average, displays the water temperature, and displays the electronic performance levels of the cell so you can see exactly how things are working. The power levels on the RJ models can be turned up and down in smaller increments. RJ models also synchronize more easily with variable-speed pumps if you plan to upgrade.
So the SJ gives you simplicity and a huge value, and the RJ gives you top of the line performance and control.

Q:
So when the time clock and pool are off, the control module shuts off too?
Also my control module is mounted in direct sunlight and exposed to weather. Is the self contain unit ok or need to be in an additional inclosure?
If I double the pool gallons to select the size of the generator is this enough?
