have youtried cutting back the time your lights are on, and if you have a FOWLR, you could leave them off for a day or two. The LFS may have a phosphate filter, this will help. I would put alot of charcoal in my sump (if u have one)....... I have put this in a cheap pair of panty hose, tied it up rinse it and let it rip. I know there are a few things that can cause the red slime, even you tap water, and certain types of food. I know some of the guys on here will have some great advice for you, I just get by with my own....LOL
