21,000 gal pebbletec pool. Arizona. Pool water currently about 88° during the day.
A week or so ago my TA was 110, and my PH was 7.6, sometimes 7.7.
I guess PH of 7.6 is "ok", but I was trying to get it to 7.5 or 7.4 - just to see if I could.
So I have been adding muriatic acid 20° Baume, 1 or 2 cups a day as recommended by pool math. But all that seems to happen here is that my TA steadily decreases so it is now at about 80. I don't think I should go lower than this. How do I get PH down without lowering TA?
I'm not really "aerating" the pool per se; although I have a negative edge that runs part time, and an integrated spa we use everyday with therapy jets.
