Fluval BIOMAX Bio Rings Filtration Media
About the Product:
Fluval BioMax rings are unique, inert ceramic rings that promote powerful bacterial growth both internally and externally. Each ring is very porous, with holes that are perfectly sized to host beneficial bacteria.
The massive internal and external surface areas allow huge colonies of beneficial bacteria to grow, making Fluval Bio-Max an ideal media for biological removal of both ammonia and nitrite concentrations in the aquarium.
