This is the ceramic filter media that forms the core of filtration in biOrb aquariums. The porous ceramic gives beneficial bacteria a huge surface to colonize — biOrb says 900g offers surface area equal to a football pitch — and those bacteria break down toxic fish waste as water passes through. It suits biOrb owners doing routine filter refreshes or adding filtration capacity. Compared with loose biological media like ceramic rings or bio-balls, it is shaped for biOrb's filter cartridge and does not fit other filter systems as neatly.

Rated 4.6 out of 5 across 11 ratings. Owners treat it as a straightforward, effective part of biOrb filtration and value the large surface area it adds.
biOrb ceramic media is the main part of the filtration in a biOrb aquarium. It helps keep the water clear and healthy. Water flows through the media, where beneficial bacteria remove toxic fish waste.
The media is full of pores for bacteria to live on. Just 900g of it has a surface area equivalent to a football pitch. More media can be added to a biOrb to increase the area for filtration.
Over time, the pores can become blocked with dirt and limescale, which reduces the available surface area. Replacing some of the media every year or so helps keep filtration efficient. Never replace more than 1/3 of the media at one time, and wait at least a month before replacing any more.
