John Collins Posted September 17 Share Posted September 17 (edited) Is this reddish-purple growth on the heater, the back of the aquarium, and the rock an unusual algae or is it something else? Any help would be appreciated. Edited September 17 by John Collins Left out Picture Link to comment Share on other sites More sharing options...
knee Posted September 17 Share Posted September 17 Is it easy to remove? What's the texture? Kinda looks like the early stages of some beard or brush algae. Link to comment Share on other sites More sharing options...

It could also be cyanobacteria but I can't be too sure cause I've never seen this in my tank. 1 Link to comment Share on other sites More sharing options...
mynameisnobody Posted September 17 Share Posted September 17 At times, I’ve tried to attack bba with hydrogen peroxide. After a day or 2, it will start to die and turn that color on your heater. Did you clean your heater? I know it’s a long shot, but it’s immediately where my brain went. 1 Link to comment Share on other sites More sharing options...
PonyPlantedTanks Posted September 17 Share Posted September 17 It’s either Cyanobacteria (blue green algae) or the very beginnings of black beard. I’ve had that exact stuff several times. It’s never gotten out of control as long as I kept on top of scrubbing it off the glass. 1 Link to comment Share on other sites More sharing options...
