I'm not sure what type it is, but I've got lots of it. When I set my tank up, the plants I bought had a little bit of green fuzz on them that I didn't think too much about. Now I've got either darkish green or very dark brown to almost black strands of algae growing off everything. The two banana plants that originally had the green fuzz have both died from it and my other plants are starting to be effected too. Any idea what causes it and how I can get rid of it? I've never dealt with this in my other tanks.
