Filter Foam Insert Hagen model 06195 for Aquarium Filter 104 — Replacement Sponge Pad

Hagen filter foam insert model 06195 is a replacement sponge pad engineered for Aquarium Filter 104. The porous foam provides mechanical filtration by trapping visible debris and particulate matter while offering a textured surface that supports colonization of beneficial bacteria for biological filtration. Designed for routine maintenance, this sponge pad restores water flow and filter efficiency in freshwater aquarium setups.

Advantages

The replacement sponge pad combines open-cell porosity for effective mechanical trapping of waste with a durable foam structure that resists premature breakdown. It is shaped to fit the Aquarium Filter 104, which simplifies installation and reduces the risk of gaps that could allow unfiltered water to pass. The foam's surface promotes biological activity, helping to maintain stable water quality between deeper cleanings.

Suitable for

• Freshwater aquarium mechanical and biological filtration maintenance
• Routine filter cartridge replacement in Aquarium Filter 104
• Reducing suspended particles and improving water clarity

Key specifications

• Material: Open-cell foam designed for aquarium use
• Function: Mechanical particle capture and support for biological media
• Compatibility: Formed to fit Aquarium Filter 104
• Intended use: Replacement sponge pad for routine maintenance
• Suitable environment: Freshwater aquariums

How to use

Turn off the Aquarium Filter 104 and disconnect it according to the manufacturer's instructions. Remove the old sponge pad and inspect the filter compartment for debris; rinse the compartment with aquarium water if necessary. Insert the Hagen replacement foam insert into the filter, ensuring it seats snugly without compressing the foam excessively. Reassemble the filter and restart it. For biological stability, avoid sterilizing the used foam with hot water or chemicals—if reusing an old sponge, rinse gently in aquarium water to preserve beneficial bacteria.

Usage recommendations

Replace the foam pad regularly as part of scheduled maintenance—frequency depends on bioload and tank conditions but typically ranges from every 4 to 12 weeks. Monitor water clarity and flow rate; reduced flow or visible clogging indicates it's time to clean or replace the sponge. When replacing, consider pairing the foam with appropriate biological media if additional nitrifying surface area is required.
