First summer in our new home with a pool. We have the tf-100 kit. Have been using the pool math app and following on here. Things have been pretty good until the last week. 25K gallon vinyl liner, Hayward t9 salt cell. Salt is 3200, TA, which we’ve been fighting all summer, is at an all time low of 100, FC 3, pH 7.2, CYA 45 so we’re adding the last of our stabilizer in a sock in the skimmer. Deep end seems cloudy. Have been running the robot 3 times a week and skimming. What else could be going on and what can we do? Clean the salt cell maybe? Any help and suggestions welcome!
