Reef-One advises against putting gravel, sand or small stones in the biOrb. Gravel is likely to reduce filtration and may become lodged in the filter cartridge casing. However, if you do use other gravel of ceramic media in your biorb or biube, make sure it is big enough not to get stuck in the bottom of the aquarium.
