So I’ve come along way from coffee brown water to Clearwater by doing the revive, followed by vacuum to waste followed by polyquat 60, AA and Sequestrant. This am I added 1 gallon 10% liquid chlorine for FC 0 CC 0, Ph 6.8, TA 120. CYA 20 Remember I am still using the test kit that I have waiting for the new recommended kit to arrive. I’m going to retest the chlorine shortly to see if any held. I do have a white film covering the bottom of my pool wondering if this is related to these sorbic acid treatment and a lower pH. What do I do next?
