Whisper Bio-Bags

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 and offer economical pricing on larger quantities.

It is recommended that you replace your Whisper® Bio-Bag® when water begins to overflow excessively from the Wonder Tube® chamber.
