This is my 10g hospital/quarantine tank. A month ago I lost 3 fish to fin rot or some fungal infection. I removed the carbon filter (left in bio filter) and treated with maracyn 1 and 2 for 5 days. After that I've cleaned the tank, added carbon filter back, done regular water changes and water monitoring. After 2+ weeks, all is well. The danios and guppies still in the tank seem fine. The water looks clear. All water parameters are perfect.
BUT I have this brown algae like substance increasing its growth all throughout the tank. It's on the glass and ornaments (incl artificial plants). It wipes easily off the glass. But when I rinsed the ornaments in the old water from a change and scrubbed gently with a brush, almost none of the brown came off.
Is this brown algae? If so, how do I treat it? I purchased a mini uv filter but it arrived damage and I'm waiting on a replacement. Will a uv filter help?
