Fluval Bio Foam 304 Aquarium Cannister Filter Media - 2 Pack

Exclusively designed for Fluval aquarium canister filters, Fluval Bio-Foam performs exceptional mechanical and biological filtration.

Bio-Foam's dense structure is very effective at trapping small particles that are not captured in the first stage of foam filtration. In addition, its intricate network of pores provides a large surface area that encourages the growth of helpful nitrifying bacteria, which is crucial for efficient biological filtration and goes a long way in creating clear and healthy water for fish and plants to thrive.

Suitable for freshwater and marine environments. 2-pack.
 
For Fluval Filter Models: 304, 305, 306, 404, 405, 406
