I'm just omitting the last part seeing this isn't so much about my fish as it is his tank. Alighieri is doing fairly well aside from the fact he's been fin-nipping a bit, but I think that may be due to stress because of this algae/frequent water changers/etc. because I just put new decorations in when I noticed he was nipping. If it doesn't improve after I get this algae under control I'll have to try and figure out what else may be wrong, but right now I'm trying to eliminate this problem.
Or he just really hates the orange mat his tank is on because he wasn't nipping at all up at school.
But I have been battling with this blue-green algae for AGES and I have not been able to eliminate it and I just don't know what to do at this point. I've tried the black out method, I've tried taking everything out and just scrubbing all residue of the cyanobacteria off - including the substrate. I've tried constant water changes while removing as much bacteria as possible manually.
I'm just at my wits end at this point because I know blue-green algae can be toxic, and it has been killing some the plants I put in there because it just coats them over. This is the ONLY tank I have that has an issue with blue-green algae so I just don't know what to do at this point. It started when I first took this tank up to school and I thought it may have just been due to an excess of phosphates in the water or something, but there was a lull when I got back home and then it came back with a vengeance. Any help would be super appreciated!
