Aquarium Advice Addict
I have a 55g with what I thought was diatom algae. Three otos later, I still have the brown stuff browing on the glass. I've waited weeks. I read peoples posts about having otos for two days and their 55g is CLEAN. I'm starting to think that the brown stuff on the glass isn't diatom but then what is it? The stuff has been there for 3-4 weeks at least possibly longer. The best description that I've heard is that it looks like it was sprayed on with a spray bottle. The stuff really hasn't grown much.
