After battling BBA for a couple months, I think it’s finally starting to subside as the plants grow in my 50G aquarium. Shortly after setting this tank up, the combination of intense lighting, too few plants, and a couple CO2 outages resulted in black brush algae to cover most of the rocks, and many of the plant leaves. I also had a brief bought with green algae, which I believe was due to an insufficient bacteria colony to help break down the organics in the tank.
Recall that this aquarium was basically started afresh, removing very old Aquasoil and replacing it with Seachem Flourite Black. I also made a couple of equipment changes, adding an inline CO2 atomizer on my filter outflow and a surface skimmer on the inflow. This has helped a longtime problem with surface scum. I’m planning to keep up on the manual removal of BBA until it’s gone. Let me know what you think of the aquascape in the comments.
