Sorry Carl, I guess I assumed too much. Although he did not say he had a heater, according to Ben:


What should my TA be?
Somewhere between 50 and 200 ppm. If you've got a heater, it usually should be lower than 150 ppm. If you've got a plaster or concrete based pool, it usually should be higher than 80 ppm.


Because I have a plaster pool and high calcium, I like to keep mine between 80-120.
