BiOrb ceramic media forms the main part of filtration in your BiOrb and is important in keeping the water clear and healthy.

Beneficial bacteria colonise the ceramic media and remove toxic fish waste from the water as the water flows through it.  You can add more media to increase the area for filtration.

Over time, these pores can become blocked with dirt and limescale reducing the surface area available. Replacing some of the media every year or so can help to keep the filtration efficient.

Suitable for use with the BiOrb Life 15L
