Is my TA too low?
I have been neglecting the cement pond and the other folks here are not up to speed.
I have been adding about a gallon of acid each 7-10 days, as I have since the pool was built, it usually lands around 7.2 and raises to 8.0 when next check.
I have tried to get them to minimize tub spill over due to the aeration.
So I am back at the helm for a bit and looking to know if I should raise the TA to like 60 then chase down the pH with acid? or is that just a circular path?
38k gallons, swg
thanks

Don't lower the pH to 7.2, only lower it to about 7.8, or even 7.9. What is the cyanuric acid level? When was the plaster done?

You should post a full set of water test results. The appropriate TA level depends on a number of factors and interacts with what your CH level should be, none of which we are able to comment on without a full set of test results. Also, how old is your plaster?
