Are you talking about the Oceanic BioCube or an exterior tank? If you're talking about the BioCube, there are plenty of cheap mods out there that changed the bioball area into refugiums.

A compartment is a compartment. In can house the bioballs or it can host anything else like chaeto, cucumbers, algae, etc... You just gotta add the lighting for it if it needs it.
