Is there any macro algae I can put in my fowlr display that looks nice but will help keep nitrates down? I have cheato in my nano in a fuge but not sure how it would look in my display tank. Is there any way I can hide it? I'm going to be painting the back of the tank black and was thinking may be some sort of hang on box that could be inside the tank drilled with a few holes made from black acrylic so you cant see the algae.
