I run multiple HOBs in my 125g for mechanical polishing only without inserting any biomedia, but I install a dedicated circulation pump to blow oxygenated water over all surfaces.

You don't need dedicated bio media in your filters if you have good oxygenated water turn over as your tank walls, substrate, decors and all contact surfaces are practically in situ bio media.

On the other hand, it is useless and may even be harmful if you have a lot of bio media in your filter but allow it clog up and not thoroughly oxygenated.
