Thanks to this website I’ve been able to get my water levels near perfect. TA started at 120 with 7.8 ph and now I got alkalinity levels to 60 with ph of 7.2. Plugged in the results on pool math premium and it says to keep adding dry acid. Is 50 the ideal TA level to get to, then should I just aerate to bring ph back up or should I just leave TA at 60 and just aerate to raise ph a bit?
