I'm at the point now where I have to add dry acid every week or so because of my climbing pH, even when there hasn't been a lot of swimming going on lately (not too much rain either).
Our TA has been pretty steady around 70. I just lowered pH from 7.7 to 7.5/7.6 the other day.
In the early season, when TA was about 100, our pH was stable, but then again, not much swimming going on at all then.
Is this a normal occurrence to have to lower pH in the mid-to-end of the season, weekly? I'm now wondering if my rising pH has anything to do with my low TA and wondering if I need to correct TA at some point in order for pH to remain more stable??
