I have a friend that has a 15,000 gallon pool. DE filter and an SWG. Everything seems to be working normally but in the last 2 weeks, he is having a recurring problem with green slime on the walls of his pool. His PH has been a little high but he is keeping it in check with acid but his chlorine levels are fluctuating. His salt level keeps going UP? How is this possible?
I'm beginning to suspect an edgy SWG unit but he just bought the SWG unit about 6 months ago but the head unit came with the house. The head unit says all is well except the high salt level.
Any ideas?????
