Posting this summers readings below. Can anyone tell me why my pH keeps creeping up. Dropping acid (love saying that, but its the legal way) every other week to deal with it, but if theres a cause I can prevent would like to know. Thanks guys! PS-before anyone asks, yes I use all TFP chems to test, no test strips or pool stores ?
