In our opinion this as one of the best bio filter mediums available on the market today.

sera siporax® is a fully biological filter material for all internal, external and trickle filter systems, and for garden pond filters. 1 liter sera siporax® provides as much settling area for bacteria as approximately 34 liters of ceramic filter material. Therefore 1 liter sera siporax® ensures more than 200 liters of biologically clean aquarium water. sera siporax® is an excellent choice for small filters.

Prefilter with sera biofibres or sera filter wool to prevent large particles from entering the biofilter.

sera siporax® provides anaerobic bacteria an extremely large amount of open-pored tunnel structures. This allows an ideal supply of the anaerobic bacteria with nutrients and a smallest amount of fresh water. There are oxygen-poor conditions within the tunnels. This makes the bacteria crack nitrate to get enough oxygen. Consequently, they continuously break down nitrate, and the aquarium water remains low in nitrate.
