Fluval filter frame for foam inserts 105/106 model A20122 (MPN FV-1220)

Replacement filter frame compatible with Fluval foam inserts sized for 105/106 units, model A20122. This frame serves as the structural support and housing for filter foam media inside compatible Fluval filter units. It keeps foam inserts correctly positioned, simplifies media replacement and helps maintain consistent mechanical filtration performance in freshwater and marine aquariums.

Advantages

The frame restores correct alignment and tension of foam media, reducing bypass and ensuring water passes through the intended filtration surface. It is designed to fit the specified foam insert dimensions and to withstand regular handling during maintenance. By holding foam securely, the frame helps prolong the effective life of the mechanical filtration stage and supports consistent water clarity.

Suitable for

• Owners of Fluval filters that accept 105/106 size foam inserts
• Routine maintenance and filter media replacement
• Freshwater and marine aquarium mechanical filtration stages
• Situations where foam media needs stabilization to prevent channeling

Key specifications

• Compatible foam insert size: 105/106
• Function: structural support and housing for foam filter media
• Material characteristics: rigid, maintenance-tolerant construction suitable for repeated handling
• Intended environment: freshwater and marine aquarium filter units
• Role in filtration: mechanical filtration support to maintain proper water flow through foam media

How to use

Remove the filter unit from the aquarium according to the manufacturer’s maintenance guidance, then open the filter casing and extract the existing foam insert. Place the foam into the replacement frame ensuring it seats evenly and aligns with inlet and outlet channels. Reinsert the assembled frame and foam into the filter housing, close the casing and reinstall the filter in the aquarium. After reassembly, prime or start the filter as required and verify correct water flow and absence of leaks.

Usage recommendations

Inspect foam media regularly and replace or clean according to water quality and bioload. Rinse frames in dechlorinated water during routine maintenance rather than using detergents or bleach. When replacing foam, ensure the frame and media are free of debris and seated securely to avoid bypass and maintain effective mechanical filtration.
