Hello - We live in a hard water area. Got the pool replastered in January and the CH has been slowly rising ever since. My husband tested it last week and he got 475 but I got 425 today (and have gotten 425 for the last three weeks). I tested the fill water today and it is 100, and with our temperatures hitting the 100's we are now topping off the pool about twice a week.
Does anyone have a water softener for their pool or is it a whole house water softener? Does it really help with keeping your CH in check over time (years)? Or is it best to try to keep PH low to counteract the high CH?
Full readings from Sunday 6/7 were:
PH - 8 (we are constantly adding acid to keep it under 8 due to the replaster. Of course we added acid after the tests).
TA - 75
