My TA was a little high (about 90-100). Following the recommendations in the Pool Calculator I lowered the pH to 7.0 and began aerating the pool on Sunday evening. Yesterday morning the pH was 7.2 and today it's 7.4, but the TA went from 70 yesterday to 80 today. I understand that 80 is an OK level for TA, but is it normal for it to climb back up so fast? I thought the low pH brought down the TA and the aeration was supposed to cause the pH to rise but leave the TA alone. Is it likely to stabilize at some level below where it was to start with? Do I need to keep the pH at a lower level for a while, or just let it rise on its own to the normal range?
