Right, quick history.
Before I discovered TFP my TA was > 190 and I was adding acid every 2 days. I spent a few days with a lot of acid and serious aeration getting it down to ~110. It sat there for a couple of months before I decided to push it down to ~60 as I was still getting pH rise on a weekly basis. Same deal. Acid + aeration. Now the pH is solid at 7.3, hasn't moved in a week and I'm not remotely unhappy with that.
I'm planning to add borates to the pool, and I have boric acid on the way. The problem (as such) is poolmath indicates that boric acid to give me 50ppm is going to drop the pH 0.29 points. So ideally I need to get the pH up before I do that. Theory might posit I should raise the pH with Borax, then add the Boric acid with a qty calculated to give me my 50ppm in total which will bring the pH back down.
That'll give me a mid-range pH, (targeting 7.5-7.6) the right concentration of borates and I won't have to add any more carbonates. Does that sound logical?
