I recently had a diatom bloom. It appears to be over as I no longer have brown stuff growing all over everything. Now what I have is green algae that slowly grows all over my glass. It will grow noticeably over a days time. I got a magfloat yesterday and came home and cleaned what was on it off. Now this evening, once again, I have a light green haze over all three sides of the tank. I added ten nerite snails to the tank to add to the three large snails I have in there but so far, not helping much. Even the big ones, when they are on the glass, don't really help much. Just leave streaks on the glass. Anything I can do to at least slow the growing if not get rid of it all?
