Hey all, I suspect my SWG cell is going bad, I have a t cell 15 with aqua rite control board. The negative diagnostic shows 3100ppm salt and the positive shows 2400ppm. I tested and it is around 3100ppm. Do I have a bad cell or a board issue? The Amps and volt readings are what they should be for each respective salt level but not sure why the difference in salt levels? I added salt and the neagative increased as expected but the positive only increased slightly. Any insight would be appreciated.
