## Summary description

Replacement sponge cartridge for the TetraTec BF 1200 internal aquarium filter. This foam insert provides mechanical and biological filtration by trapping debris and supporting beneficial bacteria. Designed as a direct spare part for BF 1200 units, it keeps water clear and helps maintain stable aquarium conditions for freshwater setups and planted tanks.

## Long description

Replacement sponge cartridge for the TetraTec BF 1200 internal filter that restores mechanical and biological filtration in compatible aquarium systems. The foam insert is designed to trap suspended debris and provide a porous surface for beneficial bacteria, helping to maintain water clarity and stable water parameters in freshwater and planted tanks. As a direct spare part for BF 1200 units, the cartridge fits into the existing filter housing without modification.
Advantages
The foam cartridge combines mechanical particle removal with biological colonisation in a single element, reducing the need for multiple media. Its open-cell structure captures dirt while offering a high surface area for nitrifying bacteria, which supports ammonia and nitrite breakdown. The replacement insert is dimensioned to match the internal filter chamber for secure placement and consistent flow characteristics. It is washable and reusable for several maintenance cycles, reducing waste and ongoing operating costs.
Suitable for
Freshwater aquariums using the TetraTec BF 1200 internal filter
Planted tanks where gentle filtration and biological stability are required
Routine maintenance and periodic replacement of worn or clogged filter media
Key specifications
Type: Open-cell foam sponge for mechanical and biological filtration
Compatibility: Designed for internal filter housing of the specified model
Function: Traps suspended solids and provides surface for bacterial colonisation
Maintenance: Washable and reusable; replace when permanently clogged or degraded
Intended water type: Freshwater aquaria including planted setups
How to use
Switch off and unplug the internal filter before opening the housing. Remove the old sponge cartridge and inspect the filter chamber for any accumulated debris. Insert the replacement foam insert into the filter housing in the same orientation as the original part, ensuring a snug fit without deforming the sponge. Reassemble the filter, restore power, and monitor flow to confirm correct installation. Perform regular rinsing of the sponge in aquarium water during scheduled maintenance to preserve biological colonies and prolong service life.
Usage recommendations
Rinse the sponge gently in removed aquarium water rather than tap water to avoid killing beneficial bacteria. Replace the cartridge when the material shows irreversible compression or damage, or when rinsing no longer restores acceptable flow and water clarity.
