Penn-Plax Cascade Bio-Floss Replacement Poly Fiber Fish Floss Pads, 2 Count

Keep your tank water clean and crystal clear with Penn-Plax Cascade Bio-Floss Replacement Poly Fiber Fish Floss Pads! Specially designed for Cascade Max Flow Canister Filters (each sold separately), these pads allow you to easily replenish media without cutting to size and fit directly into media trays. Perfect for your freshwater or saltwater aquarium, this bio-floss helps clear up discolorations and reduce foul odors by physically trapping tiny particles of detritus, including fish waste, uneaten food or decayed aquarium plant materials, while establishing and maintaining healthy, crystal-clear water within your tank. Along with mechanical filtration, these replacement pads promote the colonization of beneficial bacteria, help regulate ammonia, nitrate and phosphate levels, prevent clogging of finer filter media so they perform better—plus, they improve overall filtration, extend the lifespan of other media and the filter itself (sold separately). This is also great for use with aquatic turtles and aquatic amphibians.
