Bradleyofkansas and mknauss,
I was going to start a thread to ask why my pH is drifting downward from 7.6 to 7.2, while my TA is stable at 110, where it's always been.
Due to the grandkids going back in school, cool nights down to 45-50 degrees, and somewhat rainy weather, our pool has remained unused and covered (to conserve heat) for the past 10 days. Time to get that cover off and aerate, I guess.
Only at TFP does your question get answered while you're only thinking about asking it, LOL!!!
Thanks, guys.
