## Summary description

Replacement Fluval Bio-Foam sponge insert designed for use with the AC110 aquarium filter. Serves as biological filtration media that provides high surface area for beneficial bacteria colonization while also offering mechanical debris trapping. Compatible with AC110 filter cartridge system; used to maintain water quality in freshwater and planted aquariums by supporting nitrification and reducing particulate load.

## Long description

The Fluval Bio-Foam sponge insert for AC110 filter is a replacement biological filtration media engineered to fit the AC110 cartridge system. It combines a porous foam structure that provides a large surface area for colonization by beneficial nitrifying bacteria with a fine mechanical layer that traps suspended debris. The insert is intended to support biological filtration in freshwater and planted aquaria, helping to maintain stable water parameters by promoting nitrification and reducing particulate load.
Advantages
The Fluval Bio-Foam insert offers a balance of biological and mechanical filtration in a single component. Its open-cell foam supports rapid establishment of beneficial bacteria and promotes gas exchange, while the finer outer foam helps capture visible particles and reduce cloudiness. The insert is pre-shaped to fit the AC110 cartridge housing, simplifying replacement and routine maintenance without the need for cutting or trimming.
Suitable for
 Freshwater aquariums using the Fluval AC110 filter system
 Planted tanks where biological stability and low particulate levels are desired
 Routine cartridge maintenance and staged media replacement
 Hobbyists seeking a combined biological and mechanical media solution
When it may not be suitable
This insert is designed specifically for the AC110 cartridge system; it may not fit other filter models or non-compatible housings. For aquaria requiring chemical filtration (for example, adsorbing dissolved organics or medications), this biological/mechanical insert does not provide activated carbon or other chemical media functions and should be used alongside appropriate chemical media if needed.
Key specifications
 Media type: open-cell biological foam with finer mechanical outer layer
 Primary function: biological filtration and mechanical debris removal
 Compatibility: shaped for Fluval AC110 cartridge housings
 Intended use: freshwater and planted aquariums
 Installation: replacement insert, no trimming required
How to use
Turn off and unplug the AC110 filter before opening the cartridge housing. Remove the old cartridge and lift out the existing media. Insert the Fluval Bio-Foam replacement so it seats correctly in the cartridge chamber, ensuring the finer foam layer faces the incoming flow if orientation is marked. Reassemble the cartridge housing, return it to the filter, and power the unit. Allow several days to weeks for bacterial colonies to establish; avoid complete media replacement in heavily stocked tanks unless staging with seeded media to maintain biological stability.
What to consider before purchase
 Ensure your filter model is Fluval AC110 or a compatible cartridge system
 Determine whether you also require chemical media for adsorbing dissolved compounds
 Plan maintenance frequency: foam inserts may require rinsing or periodic replacement depending on bioload
Usage recommendations
For best results, rinse the insert in dechlorinated water during routine maintenance to remove trapped debris while preserving beneficial bacteria. For heavily stocked aquaria, consider staggering media changes to avoid sudden drops in biological filtration capacity. Combine this bio-foam with separate chemical media if control of dissolved organics or medications is necessary.
