- Enhances biological filtration
- Effectively captures small particles and debris
- For Freshwater and marine environments
- Increased surface area helps the growth of beneficial nitrifying bacteria
- Traps small particles that are not retained by the first stage of foam filtration
12 bio-foam pads made for the Fluval FX4, FX5 and FX6 filtration systems. These 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.
