Hello pool experts! I stumbled upon your site while trying to find help for my ailing salt water pool....my pool builder seems to be too busy to respond to my 6 phone calls that I put out to him!! We seem to have this flaky blackish-greenish stuff floating around in the pool and endless dirt at the bottom! Green slimy walls continue to haunt us day after day and even though we have done chlorine boosts the level is still registering 0 with a general test kit!! What the heck?? We can not seem to figure this thing out! My hubby is bout ready to fill the darn thing back in with dirt I was looking for some solutions in the search bar, but the site said I am restricted from seeing what others have to say on the topic?
