I am trying to lower my pH but do not seem to be making any progress. Test results as follows:
FC - 4.0
CC - 0
CYA - 40ish
PH - 7.9
Trying to get the pH down to around 7.6 or so. Per the pool calculator I should add 21 oz. muriatic acid. I have added about 20 oz. so far but it has not seemed to drop at all. Granted it is a color test, so subjective, but I have not really noticed a change in color of the dye test. I am somewhat apprehensive about adding too much acid to the pool so before going further dumping more in, I thought I would get some input. Am I missing something or should I keep going with the acid?
