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.

I would recommend it
This was recommended to me by half the people on my street and it didn't disappoint. Put it in myself, and the pool has turned into a well-oiled machine that I don't have to mess with.

Working Great!
After about one year of struggling with another brand of chlorine generator, I finally bit the bullet, did my research, and purchased the RJ-60 Plus Salt Chlorine Generator. Water has cleared up beautifully and I haven't had to shock the pool in the heat of the summer since installed. Works beautifully so far!

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: what is the advantage of RJ-45 plus unit over the RJ -45?

Asked by: Floyd - 4/8/2017
A: The RJ-PLUS models have a different cell which is longer lasting (compare the regular model with 11,500 hours of use vs. the Plus model with 15,000 hours of use). Since it is longer lasting, it has a longer and better warranty.

Q: Does this unit run on 120 or 240 volts?

Asked by: Rick - 3/23/2017
A: This unit can work on either voltage. Most pools utilize 220V, so the default setting for this salt chlorinator is 220V, however instructions show you how to change the input power setting to 110V if that is what you need. For this equipment, there is no advantage to either voltage, you just want to match what your pump is using.

Q: I have two questions. First: Can this system re-place my existing Jandy/Zodiac nature 2 Fusion Soft System without changing plumbing? Second: I have a 38,000 gallon pool with a Jandy VS Stealth pump that I am currently replacing too. What size salt system/chlorine generator should I purchase?(after 4 years of trouble shooting and constant maintenance and cost, I have come to HATE Jandy products).

Asked by: bikingmomma - 6/24/2017
A: For 38,000 gallons, you would at least want this RJ45-PLUS size system, but you might also have a better experience if you get the larger RJ60-PLUS. More power is always better.

Q: Currently I have aHeyward swimpure controller & T-cell 9. I saw where the Rj-45 was compatible with theheyward aqua rite system. Do I have to do anything different to change my system?

Asked by: Dwight - 5/4/2017
A: The CircuPool RJ system can easily replace your Hayward. The cell has the same size, fittings and threaded connections. The control box should wire up the same way. Switching the whole system usually takes just a few minutes.

Q: How many hours do I need to run the pump to get the 2lb of chlorine?

Asked by: deke - 8/17/2017
A: Saltwater chlorinator manufacturers list the chlorine output in lbs/day. In other words, the power listed is the maximum level, so you typically want a system whose listed maximum number of gallons is 1.5x to even 2x the pool size. For more information about sizing, this is a good link:

Q: I have a 35,000 gallon in-ground pool. I'm not sure which size salt generator I should purchase? Thank You

Asked by: ciso305 - 11/2/2017
A: For a 35,000 gallon pool, this RJ45+ unit would be a good choice. It is rated for up to 45,000 gallons max, so it should give you plenty of extra power when needed.

Q: I just installed a GFS Generic Flow Switch that I bought from your website. Will it work with this system, or will I need to replace it with the unit that comes with the package?

Asked by: Steve Baker - 6/21/2017
A: That is a fully compatible flow switch. It is the same flow switch that works with many different brands and models, so there should be no issue there.

Q: How do you estimate Pool Capacity of a kidney shaped pool?

Asked by: Dre - 10/16/2017
A: Kidney shape and free-form pools are always hard to estimate. For ease of calculation, I recommend treating it like an oval: multiply the length x width x average depth x 6.7 to get the number of gallons. For pool system capacity, it is better to be on the safe side and over-estimate the size rather than under-estimate.
