Tetra Whisper Bio-Bag Cartridge replacements complete the Whisper Power Filter package for a clean, easy-to-maintain aquarium. Filled with ultra-activated carbon, these ready-to-use disposable filter cartridges remove waste particles, odors and discoloration for crystal clear water.

  • Genuine Whisper filter cartridge replacements
  • Keeps water crystal clear
  • Removes odors & discoloration

Bio-Bag cartridges are tough on the debris that makes aquariums nasty. Ultra-activated carbon absorbs odors and discoloration and dense, dual-sided mesh catches debris and fish waste better than other brands to keep your fish tank clean. Replace cartridges once a month for maximum filter efficiency.

Tip: Replace Bio-Bag cartridges when water begins to overflow excessively from the Wonder Tube chamber.
