Tetra Whisper Bio-Bag Cartridges complete the Whisper Power Filter package for a clean, easy-to-maintain aquarium. The Tetra Whisper Bio-Bag multi-packs come un-assembled and offer economical pricing on larger quantities.
Filled with Ultra-Activated carbon, the ready-to-use disposable single packs remove waste particles, odors and discoloration, and are easily changed once a month. It is recommended that you replace your Tetra Whisper Bio-Bag when water begins to overflow excessively from the Wonder Tube chamber.
