Product Description

The Fluval Nano Bio-Foam Filter Media Insert was specifically designed to fit inside the Fluval Nano Filter. It works to capture debris for effective mechanical filtration, plus it has large surface areas that encourage the proliferation of friendly nitrifying bacteria, which provide efficient biological filtration. The Fluval Nano Bio-Foam Filter Media Insert fits perfectly inside the filter chamber to prevent debris bypass. Bio-Foam allows efficient water flow, less clogging and long-lasting filtration.
