Fluval Biomax bio rings have a complex pore system where beneficial bacteria can thrive.
Biomax rings allow ideal water movement throughout the media, to ensure optimal contact time for efficient biological filtration.
Biomax is the optimal environment for beneficial bacteria and has more capacity than most biological filter media media.
It reduces and controls ammonia and nitrite and is suitable for freshwater and marine environments.
Ideal for use in all Fluval filters, 105,205,305,405, and FX5.
