Generic BioMaster 20ppi Filter Foam

The coarse sponge serves for the mechanical and biological filtering of your aquarium, making it an essential component of the BioMaster filter system.

The coarse pore structure gives a large surface area, guaranteeing relatively high and even water flow velocity. This means that it is particularly suited to biological filtering in the aerobic area.

The open pores of the coarse filter sponge were made without the use of chemicals, meaning that there is no residue.

• Best mechanical and biological filtering characteristics
• Homogenous structure, guaranteeing even flow conditions
• No chemical residue
• Suitable for use in freshwater and saltwater aquariums
