This is the only type of gravel that should really be used with the biOrb due to the design of the filters. I tried using regular aquarium gravel and all the debris from the fish got stuck in it. Also, small aquarium stones will pass through the biOrb filter and accumulate in the center circle, causing further clogging. This environment allows debris to fall through and be sucked back through the filter.
