Okay! Took me awhile, it's been a crazy week!
My chlorine is 10, PH 7.5, total alkalinity is 270, total hardness is 230 and the CYA is 100.
I have a 12' round above ground pool. The pump is a skimmer model F700C, not sure of brand- it uses the cartridge filters.
It is SLOWLY clearing...can almost see the bottom of the ladder. Every time I clean the filter it's full of white sludgy stuff that I can spray off with the hose.
Thanks for your help!
