FLUVAL 204-206/304-306 Foam Filter Block

These foam blocks are shaped to sit neatly in Fluval 204-206 and 304-306 canister filters. They trap larger debris as water passes through, giving you reliable mechanical filtration, and they also give beneficial bacteria a place to settle.

The snug fit stops water slipping past the media, while the open pore structure keeps flow moving freely and slows down clogging. Suitable for both freshwater and marine tanks.
