I have a sump running under my tank with bio balls as the main bio filter media.
I have read conflicting reviews about them so just wondering if I would be better of putting live rock in there instead? I have too much in my tank do wanted to move some out and thought it was better than wasting it.
If I did change, would I need the same volume as I have in bio balls?
Cheers
