I am having a problem with blue green algae (BGA) in all of my tanks. Disgusting stuff, smells bad, won't be eliminated easily. I am doing maracyn treatments in the two 10 gallons, and am still wondering what to do in the 20 gallon tank. The 55gallon had it really bad, but I was able to switch some things up and it's not a problem anymore in there.
I think the BGA is being such a problem because the tanks are pretty low water movement, and they're heavily planted. They are simply too clean and too still - very low nitrates (which I hear BGA loves since they can fix their own nitrogen), decent light, and ferts. I have increased the circulation on all the tanks, and everyone seems ok...thank goodness for short finned bettas. Hopefully that will help even after the maracyn tx is over.
Anyway, my question is: have you ever gotten this stuff in your smaller betta tanks? What did you do to get rid of it and keep it away? I am looking for any ideas beyond nuking the tank with maracyn, which I am doing but I hate. I just don't know what else to do. Thanks in advance!
