Opened pool 2 weeks ago and water was clear enough to see bottom. Had the same layer of brown dirt at bottom it has had in years past, vacuum'd that to waste, SLAM'd with liquid cl, it cleaned up quickly. CYA was zero added CYA by sock method to bring to 50ppm.
But there's a slight green tint in the water that just won't clear. It's not getting better or worse it's staying the same.
Water passes OCLT. Have been running with a dose of DE in the sand filter no improvement. Have not added any algaecide, clarifier, or mystery fix in a bottle just 12.5% Cl and a little soda ash in the beginning to get the PH up. Shocked it to 20ppm three days ago, no change.
As of this AM,
PH 7.2
Cl 6ppm (fas-dpd kit with fresh reagents)
CC zero
CYA 50ppm
Pool is filled/topped off with city water it's never been a problem in years past. With all the rain we had winter/fall the pool is probably 50% or more rainwater only added ~3" of city water when opened. I don't have a test kit for metals but had water checked at 3 different pool stores (boo, hiss!) have all said "no metal" and haven't tried to sell me anything.
