Fluval BIO-FX Premium Filter Media 2 L – Biological Filter Media
Fluval BIO-FX Premium Filter Media 2 L is biological filter media designed for use in compatible canister filters, sumps, wet/dry systems, and other aquarium filtration setups. It provides surface area where beneficial nitrifying bacteria can grow as part of the aquarium’s biological filtration system.
The 2-liter size is useful for small to medium canister filters, supplemental biological filtration, planted aquariums, community tanks, and aquariums with moderate bioloads. BIO-FX can be used in freshwater and saltwater aquariums when placed in a suitable filter area with steady water flow.

How to Use
Rinse BIO-FX gently before first use if directed by the manufacturer. Place the media in a filter bag, media basket, sump chamber, or other appropriate high-flow area of the filtration system.
Do not replace all established biological media at one time. Biological media can hold beneficial bacteria, so gradual cleaning or replacement can help reduce disruption to the aquarium’s biological filter.
Usage & Maintenance Tips
- Place BIO-FX where aquarium water can flow through the media
- Rinse before first use if recommended on the package
- Rinse established media in removed aquarium water during maintenance
- Avoid rinsing established biological media under untreated tap water
- Do not replace all biological media at the same time
- Replace or clean media when it becomes clogged with debris
- Use with mechanical filtration to help prevent debris from clogging the media
Important Biological Filtration Note
BIO-FX can support beneficial bacteria, but it does not instantly cycle an aquarium or replace proper tank cycling, water testing, water changes, correct stocking, or routine maintenance. Ammonia, nitrite, and nitrate should still be monitored as needed.
Mechanical filtration before biological media can help keep BIO-FX cleaner by reducing debris buildup. Chemical media may also be used separately when needed for specific water quality concerns.
