I know I shouldn't close my pool with the pH low, but will it hurt to close with it high? I've put a couple of gallons of muriatic acid in and aerated to get my TA down to 120 in the last 2 weeks, but the pH drifted back up to 8.2 from 7.8 when I put my maintenance dose of chlorine in. My water temp is down to 62 and I'm ready to close. Will the pH go even higher when I shock? Can I deal with this pH problem when I open in the spring?
