I am starting a new intex 14x42 ultra frame with a intex 1200 gph sand filter pump and the intex swg. I have been running the system for a week now after adding salt and I have these white flakes on top of the water for the past 3 days. Otherwise the water is crystal clear. Today I added one pound of cyanuric acid since I did not do it last week at startup. I have ordered a Taylor k2006 so I can test all of the other stuff in the water but I need help about the white flakes. My pool holds 4047 gallons of water and I added 100 lbs of salt at start up. I will be installing a Hayward thru wall skimmer soon to help with floating bugs and stuff but these white flakes are driving me crazy. Help please.
