Tetra - Whisper Filter Cartridge (6pk)



The Tetra Whisper Filter Cartridge keeps water crystal clear for healthier fish.


  • Keeps your power filter running like new
  • Easy installation and replacement
  • Dense, dual-sided mesh catches debris and fish waste
  • Activated carbons remove odours and work against discolouration


  1. Rinse filter cartridge under cool tap water to remove carbon dust
  2. Open lid and insert filter cartridge into filter
  3. Replace clogged filter cartridge when there is reduced water flow out of the filter

For best results, change filter cartridge monthly.

After 30 days the carbon begins to loose effectiveness.
