Fluval 107/207 Bio-Foam+ Replacement Foam

A single replacement Bio-Foam+ block that fits both the Fluval 107 and the Fluval 207 canister filter.

Key features

• One block covers two filter sizes, so a 107 owner who later moves up to a 207 keeps the same spare
• Sits in the filter as the mechanical stage, catching the coarse waste that would otherwise clog carbon and polishing pads
• Doubles as biological media, since the foam's internal surface is where a large share of your nitrifying bacteria live
• Custom shaped for the 07 series basket, so water is forced through the foam rather than around it

Replacing it

Foam is a rinse-first item, not a throw-away one. Squeeze it out in a bucket of tank water at each service and only replace it when it no longer recovers its shape. If you keep more than one foam block in the filter, replace them on different weeks so the bacterial population is never wiped out in one go.

The Bio-Foam Max for the 106 and 107 is a different, thicker block and is listed on its own page. For value packs and the rest of the range, see Fluval. Local pickup is available at our Lethbridge store.
