Tetratec Biological Filter Foams BF 300 and 400/600 and 800/1000

Use of Tetratec BF Replacement Foam in Tetratec Internal Filters IN 300 and IN 400/600 and IN 800/1000 ensures that the aquarium water is filtered effectively. Biologically active bacterial cultures that transform harmful nitrite into the plant fertiliser nitrate settle in the filter foam. The foam structure also carries out physical filtration, removing visible particles from the aquarium filter. Also suitable for use in marine water aquariums.

• Settlement of biologically active bacterial cultures in the filter foam: harmful nitrite is converted into nitrate.
• The structure of the foam ensures good physical filtration: small, visible particles are removed from the aquarium water.
• for both freshwater and marine aquariums
