Okay guys, thanks for opening. First, I opened my pool June 30th 2006. The water was disgustingly green and full of leaves on the base of the pool. I shocked the water numerous times (about 10-14 lbs of shock was used since then) and used 1 bottle of standard algaecide and one bottle of black algaecide. The water turns clear for about a few days on the surface but the bottom is still green. i always try to push away the dirt (algae?) on the bottom of the pool INTO the filter. i tried vacuuming but that doesnt work.
this is a picture of my filter... (http://i20.ebayimg.com/04/i/06/c2/86/d6_2.JPG) *picture was used just for showing purposes, it is NOT mine, belongs to owner.

my pool is 18' wide, and 3' deep. I dont know what to do. I havent used any chemicals yet but i have purchased them. so if u guys can help and get me started it would be greatt. Thanks. -Zee.
