A week ago my TA was a bit high at 120 & PH was 7.7. I wanted to lower TA so i added the appropriate MA & TA was then 110 & PH 7. I aerated for a week & PH raised to about 7.2 (didn't increase much). I then added MA tonight according to calculator for PH to 7.0 , but will not test TA again till morning. My issue is the TA should be lower again but it is taking such a long time to get PH to rise with this aeration. Would adding borax raise the PH up but not raise TA up much or will borax just raise TA up also?
