Thanks watermom, it's so frustrating, to think I am the cause of this mess lol. I was reading on a very similar site that uses BBB method that when copper is the reason for the green water, it's usually clear green and a seqesturant? Lol will help with the color. Well ours is green and cloudy, I'm almost thinking its a copper(green water) and cloudy is the dead algae that won't filter out with my mismatched overpowered pump/filter and maybe wrong sand. Sorry for long post
