Whisper Bio-Bag Cartridges complete the Whisper Power Filter package for a
clean, easy-to-maintain aquarium. 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. The Whisper Bio-Bag
multi-packs come unassembled.
Medium Bio-Bag Cartridges fit Whisper Power Filters 10, 10i, E, J and
MicroFilter.
It is recommended that you replace your Whisper Bio-Bag when water begins to
overflow excessively from the Wonder Tube chamber.
