Fluval Bio Foam Pads are specially designed for Fluval FX4/5/6 High Performance Canister Filters.
Bio Foam Pads provide outstanding mechanical and biological filtration thanks to an intricate pore structure that offers a large surface area for the growth of helpful nitrifying bacteria.
In addition, they trap small particles that are not retained by the first stage of foam filtration.
