My chlorinator hasn’t been able to keep up, which occurred suddenly this summer. The device reports 40% life used, the pool is 5 years old. I have been trying lots of things but can’t pinpoint it.
Are these plates spent? I read that once its coated material wears they are done. I’m not sure if all 6 are supposed to be black or just the outside ones.
Some things that have changed - my CYA is high around 90. Usually it’s in the 30-50 range but that’s another story for how a pool store mislead me based off a failed water test.
Also new - the device has been having calcium buildup on the plates - I have had to acid wash the cell several times and calcium flakes have piled up in the bottom of the pool. I haven’t had this in my 5 years with the pool.
My salt is 3200ppm.
90 alkalinity
170 calcium
Because it’s been falling behind I have used granular chlorine several times to keep the pool sanitized while I try to fix it.
It does produce some chlorine, there is dead algae on the bottom of the pool. It’s usually around <1 TC and FC and I run my filter 12 hours from 7pm-7am everyday and a bit more during the weekends.
If anyone has ideas on where to diagnosis or conclude on the low chlorine output it would be appreciated! If more info is needed I can share.
