Fluval Bio-Foam for 306 & 406

Fluval Bio-Foam combines a one-two punch of mechanical and biological filtration. Shape and pore structure create a vast surface area to promote beneficial bacteria colonization. In addition to the biological benefits, it also adds a second layer of mechanical filtration to back up your initial mechanical media. Made for the Fluval 306 and Fluval 406 canister filters.
