The salt level appears to be rising on it's own! I converted my pool to salt about a year and a half ago and had no problems until the end of June when the high salt indicator came on. Pool store tested salt level at 4800, so I drained and refilled about 750 gallons to lower salt to 4500. High salt indicator went off and everything was fine until yesterday when the high salt indicator came on again. I have not added anything except pool acid during that time. When I first installed the SWG in April 2014 the salt level at startup was approx 3000. What could be causing the salt level to rise?
Today's test results:
Temperature = 87
Ph = 7.4
FC = 7.0
TA = 70
CYA = 40
Ca = 700
Borate = 47
CSI = -0.12
Would the high calcium hardness cause a false high salt reading? Also, CYA was at 70 at the beginning of July, I'm surprised to see it disappear so quickly is that typical in Phoenix or could it be caused by the solar heater or something else? Should I even worry about it or just keep adding more to keep it around 70?
