Instructions

Penn-Plax Cascade Bio-Sponges & Bio-Floss

These media replacements ensure optimal colonization of beneficial bacteria and provide mechanical filtration, promoting a healthier environment for your fish. They help maximize your filter’s efficiency while keeping water crystal clear.

Efficient Water Filtration Made Simple

Easy-to-use Cascade Bio-Sponge filter packs fit in Cascade canister filters, as well as Eheim Ecco and FilStar canisters. The precisely cut filters encourage growth of aerobic bacteria, which prevent cloudy water and harmful conditions for your fish.

Superior Mechanical Media for Filtration

Specially designed for Cascade canister filters, Bio-Floss Pads trap small debris like fish waste and decayed plant material to prevent water discoloration and unpleasant odors. They also support the growth of beneficial bacteria for cleaner water.

Optimize Filtration & Extend Filter Life

These two filter media options not only improve overall filtration but also extend the life of your filter by reducing blockages and increasing the efficiency of filter components. For best results, use both in your freshwater or saltwater aquarium.
