I had been keeping my TA at 90-110 based off Pool Math. Keeping it at this level i found that my pH wouldn't hold steady. I was told that the 100 target for TA is just a default in Pool Math and isn't whats recommended for my pool. I was having to always add acid to lower it down from 7.6-8.0. I learned that the TA at the levels i was keeping it at was the cause of the pH always wanting to climb. I later found out from Pool School that I should be keeping it at around a 70. So with advice from the great members on here I was told to add enough acid to lower my pH to a 7.2. I did this, the next day the TA was a 90(was 110) and pH was a 7.3ish. The following day my TA was still a 90 and pH was perfect at 7.5.
With that being said if my pH still continues to climb should I do another acid drop to 7.2 to "burn" off some more TA? But its my pH stays at a 7.5 that would mean my pool likes to have its TA at a 90 right, and dropping it to 70 shouldn't be needed?
