Aquarium fish
The Tetra Whisper Bio-Bag Filter Cartridges Large are designed to work seamlessly with Tetra Whisper filter large units and 20-60 gallon aquarium filter setups. These pre-assembled filter cartridges are easy to install, with a no-mess, low-dust design that makes maintenance a breeze. Compatible with IQ, PF, 20i, 40i, and ReptoFilter models, these cartridges ensure a trouble-free change every 3-4 weeks.
With six-layer media, these filter cartridges work harder to provide clear fish tank results. The dual-sided mesh traps floating debris, while activated carbon clears up yellow water and odors. Activated alumina soaks up algae nutrients, reducing the need for frequent scrubbing. Zeolite and ceramic keep the pH stable, creating a healthy environment for your aquatic friends.
