I'm still trying to get my in-ground pool open for the summer: 21K gal plaster, Polaris 380 pool cleaner with PB-4 booster pump, Sta-Rite P4-R6 pump, Triton II TR60 sand filter. The pH level hovers around 7.6-7.8, alkalinity at 80 ppm, and Cl shock level of 10 ppm. The pool filter runs 12+ hours each day, and the water is still a milky white with suspended solids. Use of a clarifier flocculant doesn't seem to do anything. I test twice a day, morning and evening with new OTO reagents so I don't think the test kit is faulty.

Last year, this milky white state only lasted for 1-2 days before the water turned clear and blue. This year, it's been almost a week and no clear blue water in sight as of yet.

Any suggestions would be greatly appreciated.
