About This

• 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.
