Cloudy Water - 12000 gal Fiberglas pool

[Lou9art]

Week ago after three years filter element in my PLM150 was replaced, in the meantime the cloudy water got worse. I didn't help by keeping solar cover on all this time, Just read where gases were trapped in placed back into water resulting in low PH, High TA cloudy water. Yep that what I got. The solar cover has been off two days now and I'm running the filter most of the time, slight improvement. At thevtime I took this settings about an hour ago, I can just see the bottom on my 5 ft side, any helpful hints for next steps, I usually learn these type of things by baptism by fire. My settings are FCI 1, TCI 1, ACK 180, PH 7.8 TH 100 CYA 100, Appreciate any words of wisdom for the forum....Be well, I've been baptised. Lou
