So for the past few weeks my tank has been overrun with brown algea. My fish seemed to be stressed out because of it. I have be doing 50% water changes twice a week and in a few days it comes back just as bad. I have/had a BN pleco but I haven't seen it in a few weeks. That would be the second pleco my cichlids have killed. I dunno what to do....

Brown algae appears when nitrates are high. Thanks JD for that tip! Anyway things that can raise nitrates are filters needing cleaned, plants decaying in the tank, or overfeeding. I had this too and cut way down on it by realizing I feed them too much. I also lowered the temp a little. I think it helped. When I raise the temp the algae grows faster, be it green or brown.
Anyway, if the filter's clean the substrate's clean and you don't have plants dying in there it would almost surely be they're not eating all they're given. Maybe observe them close during the next feeding and see if that's the case.
My cichlids kill plecos but usually the rubber lip ones. They haven't murdered the albino BN ones. At least not yet.
