Heres where im at, pool is plaster, 18,500 gallons and just under one year old.
I have been on BBB since day one so Im pretty sure ive got this process down.
Tests as of today TF100 Kit, new chemicals;
TA 190 (high)
Looks like I need to lower my TA, by pool calc I get adding 99 oz of MA and areation to get to 7.1 . Correct?
Any clue as to how long i need to hold this low pH?
