I have a pentair IC40 my pool was built in October so it isn't even a year old. I have the Easy Touch system decided I better clean the cell today. So I put the cap on it and poured the mixture in the cell didn't foam at all so I just washed it back out and put it back on. Pluged it up and turned to the pump on for about an hr to make sure it wasn't going to leak. My salt level was 3600 before I cleaned the cell now it says the level is 4300. Is this a probleam? I need to get a good test kit for salt what do you recommend?
