last week I had no chlorine even though been adding ,having to scrub at algea patches everday.My ph is low I have 4 pucks in the skimmer 6 in an inline and I shocked it yesterday. I think I am getting to much acid and not enough stabilizer..... The sun is beating down hard , Houston in a drought , it 99 degrees everyday.....readings FC 1.0 PH 7.2 CC1.0 TA100 those are my only tests on my kit .......think I need stabilizer
