I have a new plaster pool about month old. First couple of weeks used lots of acid to lower the TA and finally got it where wanted. Took about 7 gallons of acid.
Anyhow I find myself having to add acid now just because of PH. PH creeps up to 7.7-7.8 range and every couple of days I find myself adding pint or 2 of acid. I don't mind doing this but am very worried I'll end up dropping the TA.
So how to drop the PH without dropping TA ?
