My aquarite SWG is showing wildly varying salt levels. Today it was 5,100 - 5,700 on the instantaneous reading. A few days earlier is was showing 2,400. I had it tested at the pool store and the reading was high at 4,300. Why is the aquarite so far off from the actual reading? The system has a t-15 cell. Voltage reading is 25 volts and the current is around 8 amps.
Any thoughts?
