My Pentair intelli chlorinator is putting out a white flakey substance into the pool….the chlorinator is 3+ years old. I’ve had to clean it once per month recently as the unit builds up a deposit resulting in the unit not working. I’m thinking the unit is failing. I had a high salt level (I.e. 5900 ppm until I drained some water from the pool…now at 4000, but chlorinator is having problems. Could the high salt level have damaged the chlorinator?
