Hi

I have been posting on another part of the forum. I have the same stuff. Mine started in July, really right after I put the pool up. I just thought it was dust/dirt from trees, and dirt/clay rd. I have been fighting this mess for awhile. Chlorine is above 25 for at least three days. Did dump 1/4 of water this morn and refilled. Been sweeping/vacumming. ETC. I do not have a way to backwash/ have a vinyl pool with the pump that came with it. I do have a new filter in it. Ok, it was like mentioned until I left to help dd with new baby. DH forgot to keep the chlorine up ..well when I came back it was dark green thru the whole pool. My pool today is a pretty blue with cloudy substance but notice the brown gunk when I sweep. Just like described. Ok, keep chlorine up but what happens when I let it drop back to swimming level, will that brown stuff come back? I havent got rid of it yet either. I do not cover it, I do live in the country, and my bro in law has his in full sun and he has it too. He does not cover his either. (lives next door) I havent been able to swim in the last two wks. I really would love to use the pool before cool weather sets in here in NW Fl panhandle. Thanks for any help. Oh, what is FLOC? And where do I get it? Thanks.
