I've been trying to maintain a pH of 7.2-7.5, but it keeps rising and I have been adding 2-3 cups of muriatic acid every other day just to keep it in the range I want. In fact, I got a 7.8 reading today, so I added a good splash of acid.
I do notice my TA started at 100-110 or so, and when I started adding more acid to keep pH in the low end of the range, the TA came down to 70 (over a few weeks). Should I increase TA to keep the pH stable? I'm hesitant to raise TA because if I do, won't that put upward pressure on the pH - something I don't want at the moment?
