Is it possible since I am starting to consider removing the bio balls to turn that into a refugim from what I have already seen doing my research besides adding more space to it what I have now could almost fill the spot with some minor adjustments for a refugim tank????
I guess I am really wondering what to do with all the space that will be free if I remove all the bio balls?
