Fluval Foams capture large particles and debris for effective mechanical filtration, the crucial first stage in the filtration process. They are custom fit to prevent any areas of waste, they have a pore size that allows efficient water flow with less clogging for long-lasting filtration.
These inserts also enhance biological filtration, as the surface area will promote biological filtration.
For freshwater and marine environments.
For Fluval filter models: 404, 405, 406.
