Broken record question, but I can not seem to keep the pH stable in my pool. I understand that TA is a pH buffer, and 80-120ppm is the range. TA is at the bottom of the range at 85ppm, I have not tried raising it toward 120ppm because from the spa world higher TA means the pH rises higher in the 8 range once it hits 8 but the trade off is it rises slower? I do have a CYA problem I am trying to ride out not sure if that is affecting the pH...the CYA level is at 90ppm and I am now on 100% liquid chlorine until it drops below 50. I keep the FC higher to compensate the CYA while I ride it out. I keep adding cup after cup of acid based on pool math and it works but never holds. Suggestions?
