Product Details
✓REPLACEMENT FILTER MEDIA: These Bio-Sponges are specifically designed for the Cascade 170 Fully Submersible Internal Filter (CIF4), and serve as a replacement for when it’s time to cycle out filter media.
✓PHYSICAL & BIOLOGICAL FILTRATION: These replacement Bio-Sponges optimize the colonization of anaerobic bacteria, along with providing mechanical filtration that traps large particulate matter.
✓2-PACK: The package contains 2 Bio-Sponges. Although they are disposable, they can be reused time and time again. Simply clean the Bio-Sponges in a separate container within some of your aquarium’s water. This allows for the colony of anaerobic bacteria to remain intact within the Bio-Sponges.
✓MEASUREMENTS: 1.2” (L) x 1.3” (D) x 1.6” (H) each.
✓SHOP PENN-PLAX FOR ALL YOUR PET’S NEEDS: Penn-Plax is a manufacturer and distributor of top quality pet supplies, who specialize in creating excellent pet products for animals, both great and small.
