Specifically designed to fit inside the Fluval Nano Filter, Fluval Bio-Foam captures debris for effective mechanical filtration. It has large surface areas that encourage the proliferation of friendly nitrifying bacteria, which provide efficient biological filtration.
Custom-sized, it fits perfectly inside the filter chamber to prevent debris bypass. Bio-Foam has a pore size that allows efficient water flow, less clogging and long-lasting filtration.
