CircuPool® Universal40 Saltwater Chlorinator - Complete System with 40k-Gallon Max Cell - Compatible with existing Systems,Titanium Cell & 4 Year Warranty

I bought the CircuPool 55K gallon chlorinator in May 2024. It was relatively easy to install, I did it myself in a few hours.It's November 2024 and I noticed my pool had some yellow algae in it. I checked the chlorinator and it had turned off stating that the cells needed maintainance. I disconnected the chlorinator using a large plier like oil filter wrench, took 2 minutes. Then I found the old cleaning cap from my old sucky pentair chlorinator that this replaced, found the pentair cap fit perfectly. So I propped up the CircuPool chlorinator and filled it with a 1-4 mix of muriatic acid and let it sit. It didn't look that dirty, but I did notice some fizzing.I gave it 15 minutes until the fizzing stopped, poured the used muriatic acid down the toilet. Then flushed the CircuPool unit with water. Reconnected everything, and it was producing chlorine again. So for my 30K gallon pool, looks like I have to clean the chlorinator about every 6 months. That's reasonable, having to clean was expected.I like that I went oversized on the chlorinator, I run it at 20-30% power and you can smell the excess chlorine being produced in the water. I live in Florida and its hot, lots of sun to burn up the chlorine, lots of rain to dilute the water, and this thing has really made my life easier and I don't get any yellow algae when the chlorinator and my pump is working proper. All I generally do is add Muriatic acid every couple weeks, about 1/3 gallon, and the pool stays nice and clean and sanitary with the right PH. I do have Vingli pool cleaner as well, inexpensive and it does a good job at sucking up debris on the bottom.One feature that I like about the chlorinator is the FlowSwitch. If the water is not circulating, then the chlorinator shuts off. This is especially helpful because I get a lot of power outages that trigger my pentair pump to shut off. If power comes back on and without that flow switch, the chlorinator would run without any water pump circulation which I think shortens the chlorinator life. I really wish my pentair pump had a battery backup or something, but otherwise its been a very reliable pump, going on 8 years now.One other thing I like about this chlorinator is that it requires much less salt than my old Pentair model. I actually had to drain 1/3 of the pool water out when I first installed it as the pump read that the salt levels were too high. Added back fresh water, things have been great since.No one paid me for this review, I've burned plenty of vendors where necessary. I spend a little time writing reviews as I find they really help me when choosing products. I always state the product name in the review, and if a car part I always state the model and year that the part fixed. I really wish more people would do this, I find those reviews so helpful, and I always look at the most recent reviews as the first ones you see are not typically legit and created by the vendor or their friends.Happy Thanksgiving to everyone. Take care.

This was a change from my old Hayward system. I chose this based on reviews and price, as it was $600 less than Hayward just for the system itself, and the warranty lasts 4 years rather than 3, even though it’s prorated. While I can’t review it for longevity yet, I will tell you I like the window that allows me to see salt value without opening the box. It was pretty easy to install, and within minutes was reading values and working perfectly. I’m not sure about this, but I think Hayward requires you to have their system professionally installed to use the warranty. Price of the Hayward system alone was over $1800, and pricing for installation added $800 more, for a total of $2600. This one was about $1100. No brainer to me.

So far so good!. Easy installation and a 100% DIY, my pool water is crystal clea. directions are clear. Customer service are very helpful, thank you john and GM sonny adams to answer all my questions and fulfill my request.

I have had the unit installed a little over a year. Install went fine though it took several days after the salt level was good before it accurately reflected the salt level and started making chlorine. The maint light came on in the fall for cleaning and the cell cleaning was performed per instructions. However the maint light still periodically flashed on/off. Now for the bad part. We went out of town, and when we left the chlorine was reading 3500 -- pool has been in service since May. When we returned the chlorinator was not producing and now indicated low salt. I took a sample to Leslie's pool and the salt was low. Performed another cell cleaning based on tips in the manual even though there was zero residue visible. Added salt 3 weeks ago and after testing the level was 3800. After about 2 weeks the salt updated to 2800 and the unit started producing salt. Lasted about a week and now it says the salt level is 2500 when in fact it is 3300. I have exhausted all fixes found in manual and online. It is maddening to be adding chlorine to a pool when I spend so much for the chlorinator. I. Going to call service today after waiting on hold 45 minutes last time and finally hanging up.I am updating back to 2 stars as I finally reached support. Not an ideal process as I have to remove the cell and send it to them for testing even though the support person indicated that it appears to be the cell. Fortunately I plumbed with that section for removal during the winter with straight tube.Title 'Poor quality' as I did find other people complaining of same issue.
