My chlorine levels have been dropping but the pool is sparkly clean. SWG is not raising levels at all. OCLT is negative. CC is 0.
Today my FC in the morning was 2.5. Yesterday it was 5, the day before it was 7. That is with running the SWG 4 hours. I usually need only 2-3 maximum.
I measured the FC at the outlet and it's 4.5. Hardly enough to raise or maintain chlorine levels.
The cell is free of hard water deposits.
This same thing happened last year and I replaced the SWG and it fixed it and has been working until now. Are these Intex SWG's just garbage and only good for a year? My credit card doubles the warranty so I should get a new one for free but this just seems unacceptable to have to replace it every year.
