Fluval Bio-FX

Fluval Bio-FX is a high-surface-area biological media for canister filters and sumps, built to grow the bacteria that turn ammonia and nitrite into safer nitrate.

Key features

• Deep pores and micro-tunnels pack in more beneficial bacteria
• Made for canister filters and sumps
• Available in 2 L and 5 L sizes for different filter volumes

Use Bio-FX as the biological stage after your mechanical media; leave it in place and only rinse it gently in tank water so the colony survives. More canister filter media. Available for local pickup at our Lethbridge store.
