The Fluval Nano Fine Foam Filter Media Insert was specifically designed to fit inside the Fluval Nano Filter. It works to trap small sediments and debris for effective mechanical filtration, the crucial first stage in the filtration process. The Fluval Nano Fine Foam Filter Media Insert fits perfectly inside the filter chamber to prevent debris bypass. The foam pad has a pore size that allows efficient water flow, less clogging and long-lasting filtration.

• Works to trap fine debris
• Less clogging with pore sized foam
• Allows efficient water flow
