MarinePure GEMs

Biofilter Media

Engineered BioSurface Area

MarinePure GEMs ceramic biofilter media provide far more usable surface area for nitrifying/denitrifying bacteria than conventional products such as plastic bioballs. They additionally create a cozy microhabitat for tiny animals such as copepods. Due to their 3/4″ diameter, MarinePure GEMs fit well into smaller filter systems.
