Overview

Fluval Bio-Foam for 406/407 canister filters is a dual-purpose mechanical and biological media designed to improve water clarity and stability. The coarse foam structure effectively traps debris and suspended particles, while its porous surface provides ample area for beneficial bacteria to colonize.

This 2-pack is sized specifically for Fluval 406 and 407 canisters, making it a direct, drop-in replacement for worn or clogged foam inserts and an easy way to boost overall filtration performance.
