Sera Siporax Professional Aquarium Ceramic Rings Filter Media 15mm

Sera Siporax ceramic media is a fully biological filter material for almost all filter systems.

Sera Siporax provides bacteria an extremely large amount of open-pored tunnel structures. This allows an ideal supply of  the 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 water remains low in nitrate.

1 litre of Sera Siporax provides as much settling area for bacteria as, approximately 34 litres of clay filter material.

All sizes are packaged inside zip lock bags.

300g (1 litre)
