BioMax filter media are inert ceramic rings that are capable of supporting large populations of water purifying bacteria.
Composed of a variety of channels and tunnels, the multitude of tiny pores can support these colonies of beneficial bacteria.
BioMax is an ideal biological filter media that will make the most of any filter system due to its huge capacity to support the organisms responsible for metabolizing ammonia and nitrite.

Great Review by Derek
Nice biomedia. I use it to suppliment one of my HOB filters, and added additional biomedia to my Eheim canister. So good so far. I have no problems with ammonia or nitrates, and they seem to be long lasting. (Posted on 12/2/2014)
Nice bio media Review by David
I really like this bio media. It is highly porous and it seems to have a long lifespan. Other media seems to wear out and you have to toss it and replace it but this stuff just seems to last longer. (Posted on 11/1/2014)
