I have been using Liquid Chlorine 12.5% from Menards and notice that pH keeps going right back up after I bring it down. I use Muriatic Acid in amounts according to the Pool Calculator and usually bring it down to 7.4, then within a day or so it is right back up to 7.8 or even 8.0. Alk has been as high as 150, but has been 120 for a while now. My water is sparkling, crystal clear and beautiful. Should I bring pH down to 7.2 and then aerate to bring alk down further? Seems like I read that higher alkalinity makes it harder to keep pH in normal ranges. Am I obsessing about numbers too much? :? By the way, I love BBB. The only thing I pour in my pool is chlorine and Muriatic Acid.
