Who Are These Filter Cartridges For?
Perfect for Whisper filter owners, beginners seeking hassle-free care, budget-conscious aquarists, and busy fishkeepers who want quick and effective maintenance.
Comparison to Alternatives
Compared to bulk media, Tetra Bio-Bags offer far more convenience with slightly higher long-term costs. Unlike other brands’ cartridges, these guarantee the right fit for Whisper filters, preventing bypass issues. While canister filters are more powerful, they’re overkill for smaller tanks—Bio-Bags strike the balance of performance and simplicity.
Frequently Asked Questions
What does “unassembled” mean?
You receive the floss bag with carbon and the frame separately. Slide the bag over the frame—it takes seconds and reduces packaging waste.
Can I rinse and reuse the cartridge?
Light rinsing in tank water can extend use, but carbon cannot be recharged. Full replacement is best for optimal results.
How often should I replace it?
Every 2–4 weeks, depending on stocking and feeding. Heavily stocked tanks may need more frequent changes.
