Pool: 14,000 gallons - Plaster (white) - 3 years old - North Carolina
Salt Water generator (pentair IC 40)
Filter - Cartridge (pentair)
Last water test:
Salt: 3600
TA: 130
PH: 8
CyA: 30
CH:330
TC:2.8
FC:2.8
I am getting large white flakes on bottom of pool. I tasted one and do not think it is 'salt'. Seems smooth to the touch. I know the PH/TA is high in last test but I sually keep it pretty good. One other item is on the bottom there has been some rough bumps that has developed - looks like a wad of something got stuck to the floor - Local pool company has no clue - they recommended that I vacumn to waste get ph/ta in balance and see if happens again. I saw same thing last year and thought it was because I was putting in too much acid. These appear day after I vacummed whole pool. Is this chemicals reforming and solidifying or is it the plaster dissolving and resolidfying? any help would be appreciated.
