I think I might have a type of algae growing in my planted only tank. It looks like liitle brown hairs, but is only on the plants themselves. More specifically, I've only noticed it on the Java Fern, but I also have Indian Fern and Java Moss in the tank. I do have a diy co2 system set up on it (2 20oz bottles connected with a t adapter since there are no fish in it yet. Anyone recognize this?
