I have searched previous post regarding these white flakes. I do not have a SWG. Pool was installed in June. IG Vinyl liner roughly 17,000 gallons w/ DE filter. 1.5 HP
This past Saturday we had a party with a large pool load. The following day on Sunday we noticed white flakes throughout the water. Ran a full test and everything seemed in range. Although we had added some water before party and I the CYA was a bit low.
Test from Sunday
Using Pool calculator, I added Muriatic Acid to bring down PH and stabilizer to bring up CYA to 40 and Chlorine to shock level of 10 overnight.
Flakes still in pool not as bad.
So, I'm assuming this is some sort of residue? We've brushed and vacuumed pool. Should I bring it back up to shock levels? Is this calcium? If so, what do I do?
