Hi everyone! Just closed on a house and it had/has a swamp pool. The pool was dark green and after a local pool stores advice I added 20 gallons of liquid chlorine and some yellow or green out. At first the water actually cleared up some but it was still dark green looking. Now its kinda of a cloudy aqua color. I add liquid chlorine everyday to keep the level up. I have a cartridge filter and cannot vacuum to waste so every time I try to vacuum I clog the filter and lose suction. I tried to take the skimmer net and "scoop" out the stuff on the bottom (which I can't see) and had some success. What is coming out is a grey sludge. Thanks in advance for any help!
