I maintain a 62,500 gallon saltwater pool. Recently, the "inspect cell" light on the Aquarite came on and stayed on along with the "check salt" light. The manual says this indicates low salt. I added salt and later attempted to reset to display the actual salt ppm. Nothing changed and the reading went back to 1600-1800ppm. This pump has two T-15 cells. I had the salt level checked by a pool company which read it at 3400 ppm. Chlorine and other levels are fine at the moment. There is also a Pentair automatic chlorine off-line feeder connected to the system.
This morning, I removed both cells and cleaned them. I also installed a new filter for the pump and the flow rate is very good. I believe these cells have a 3 year warranty but they were purchased before I got here and I am skeptical that anyone has receipts. This particular pump runs 24/7/365.
Hoped someone might have some suggestions before I consider buying two more expensive cells!
