Fluval Bio Foam 1 Pack
Fluval Bio Foam 1 Pack 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.
For Fluval Filter Models: 104, 105, 106, 204, 205, 206
