About this item

• BIOLOGICAL FILTRATION: Along with providing a compact and easy-to-handle design, the nylon mesh filter bag helps create a simple solution to aquarium canister filter media replenishment.
• HELPFUL INSTRUCTIONS: If you notice that the Bio Rings are getting a bit clogged, simply clean them in a separate container with some of your aquarium’s water. This allows for the colony of anaerobic bacteria to remain intact within the porous Bio Rings.
• PENN-PLAX: your one-stop shop for all pet essentials, offering top quality products for animals of all sizes.
• MEASUREMENTS: Size = 10 Oz / Quantity = 1-Pack
• CLEAN, CRYSTAL-CLEAR WATER: The ring-filled bag helps establish a biological bed for your aquarium, and optimize the colonization of anaerobic bacteria.
