Fluval replacement sponge insert Bio Foam for Fluval 107, pack of 2

Fluval replacement sponge insert Bio Foam for Fluval 107, pack of 2 are spare filtration media designed to fit Fluval 107 canister filters. These Bio Foam inserts combine open-cell sponge structure for mechanical debris capture with a porous surface that supports colonisation by beneficial nitrifying bacteria, aiding biological filtration. Supplied as a twin pack, the sponges are intended for routine replacement during filter maintenance to help preserve water clarity and a balanced aquarium environment.

Advantages

The Bio Foam material provides consistent mechanical filtration by trapping particulate waste while its porous texture increases surface area for beneficial bacteria growth, supporting biological filtration processes. The inserts are pre-cut to match the dimensions required by Fluval 107 units, ensuring easy fit and reliable flow characteristics. Packaging as a pack of two allows staggered replacement or simultaneous renewal of media during maintenance intervals.

Suitable for

• Home aquariums using Fluval 107 canister filters
• Freshwater and lightly stocked community tanks
• Routine filter maintenance and media replacement
• Improving mechanical and biological filtration performance

Key specifications

• Material: open-cell bio foam sponge designed for filtration
• Function: mechanical debris removal and biological surface for bacteria
• Quantity: pack of two identical sponge inserts
• Compatibility: specifically shaped for Fluval 107 canister filters
• Maintenance: replace according to manufacturer guidance or when visibly clogged

How to use

Turn off and disconnect the canister filter following the filter and aquarium safety procedures. Open the filter housing and remove the existing sponge inserts. Rinse the new Bio Foam inserts briefly in dechlorinated or aquarium water to remove any loose particles, then place them into the designated tray or compartment inside the Fluval 107 canister. Reassemble the filter, restore connections and restart the unit. Observe the filter operation and water flow after installation to confirm correct placement.

Usage recommendations

Inspect sponges regularly and replace them when compressed, torn, or persistently clogged; do not use household detergents—clean or rinse sponges only in aquarium water to preserve beneficial bacteria. For balanced biological filtration, consider replacing mechanical media on a schedule that complements biological and chemical media maintenance.
