This 6-Pack of Cascade Bio-Floss Poly Fiber Floss Pads is specially designed for Cascade 700 & 1000 Canister Filters, allowing for simple and easy media replenishment. Don’t worry about cutting to size, these pads fit directly into media trays within these Cascade Canister Filters. Essential Mechanical Filtration: Bio-Floss helps clear up discolorations and reduce foul odors by physically trapping tiny particles of detritus, such as fish waste, uneaten food, or even decayed aquarium plant materials. This assists with establishing and maintaining healthy, crystal-clear water within your tank. Beneficially Convenient: Along with being a vehicle for mechanical filtration, Bio-Floss also promotes the colonization of beneficial filtration. This in return, helps regulate ammonia, nitrite, nitrate, and phosphate levels. Great for freshwater and saltwater aquariums. Proficient & Prolonging: Our Poly Fiber Floss Pads help prevent the clogging finer filter media, allowing for them to perform better at their own tasks, which improves overall filtration. On the other hand, Bio-Floss extends the lifespan of other media and the filter itself. Measurements: Package of 6 Pads – 5. 75” (L) x 3” (W) x 8” (H); Individual Pad – 6. 5” (L) x 4. 75” (w) x 1” (H).
