Tetra Whisper Bio-Bag & ReptoFilter Replacement Cartridges (6-Pack)

Compatible with Popular Aquarium Filters

The aquarium filter cartridge is compatible with Tetra Whisper Bio-Bag filters 10i/IQ10/PF10 and the Tetra ReptoFilter 20 gallons (90 GPH). This 6-pack medium replacement filter cartridge is designed to fit these models perfectly.

Ultra-Activated Carbon

Each filter contains super-activated carbon, which efficiently filters and absorbs impurities, ensuring clean and clear aquarium water. This advanced carbon also helps remove scaling buildup from the aquarium glass, keeping your tank looking pristine.

Double-Sided Mesh Technology

The filter is made of dense, double-sided mesh, designed to capture the maximum amount of debris and fish waste. By removing these impurities, it helps maintain a clean water source and provides a healthier environment for your fish to thrive.

Efficacious ABS Plastic Holder

Equipped with an integrated ABS plastic holder, the filter ensures even distribution of the activated carbon for enhanced filtration performance. This design also reduces the need for frequent water changes, saving you time and effort.

Usage Tips

Activated carbon has a limited adsorption capacity. For optimal performance, we recommend changing the cartridge every 2-4 weeks. The exact frequency may vary based on your specific usage and needs.
