Fluval Foams capture large particles and debris for effective mechanical filtration, the crucial first stage in the filtration process. Custom fit to prevent bypass, they have a pore size that allows efficient water flow with less clogging for long-lasting filtration. These inserts also enhance biological filtration. For freshwater and marine environments.

Designed specifically for the 407 and 406 performance canister filters, Bio-Foam Max is a 2-in-1 biological and mechanical media that features a rippled surface pattern offering up to 30% more area for effective filtering of waste and debris.

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
