I've been battling this brown floating stuff for a while now. I have a 29g planted tank with a Coralife light. It looks like large dust particles in the water. It settles on the plants and substrate and the filter doesn't seem to take it out (an AC 70). Is this a type of algae? If I leave a bucket of the water sitting, it settles into brown fluffy stuff at the bottom...water changes seem to make it worse by stirring it up...driving me crazy!! Any ideas?

Brown fluffy stuff settling out of the water sounds more like debris (fish waste, uneaten food, etc.) than algae or diatoms. Sand substrate?

Ya, no, it's not food, I only feed once a day (sometimes not even) and make sure it's gone in a minute or so. Filtration is in the first post. I put some polyester wool in the filter and that worked like a charm. I think the sponge is just too porous (obviously left the sponge in as well). Thanks for the replies!
