My levels are:
When I enter a pH target of 7.6 the PoolMath says to:
Add 5.1 oz of 31.45% muriatic acid
However, if I go to bottom, Effects of adding chemicals:
it says that Adding 5.1 oz of 31.45% muriatic acid will
lower pH by 0.18 and lower TA by 3. which would only take pH to 7.82
if I enter 11 oz instead, it says it will:
lower pH by 0.39 and lower TA by 6.4.
I know from prior times adding acid that the 11 oz number will take my pH to 7.6 which is where I want it.
Or am I not using this right?
