## Summary description

Tetra BF 400/600/700. Quantity per pack: 1 pc(s)

## Long description

Replacement sponge cartridge compatible with TetraTec BF 400, BF 600 and BF 700 internal filters. This foam insert provides mechanical filtration by trapping suspended particles and biological filtration by offering a porous surface for colonisation of beneficial bacteria. Designed for routine maintenance and media replacement, the sponge helps maintain water clarity and supports a stable biological environment in small to medium aquariums.
Advantages
The sponge cartridge combines particle removal and biofilm support in a single insert, reducing the need for multiple media types. Its open-cell foam structure retains debris while allowing water to flow freely, ensuring effective filtration without excessive flow restriction. The replaceable design simplifies maintenance and reduces handling of filter internals during cleaning.
Suitable for
 Replacement media for TetraTec BF 400 internal filters
 Replacement media for TetraTec BF 600 internal filters
 Replacement media for TetraTec BF 700 internal filters
 Routine filter maintenance in small to medium freshwater aquariums
Key specifications
 Material: open-cell polyurethane foam suitable for mechanical and biological filtration
 Function: traps suspended particles and provides surface area for nitrifying bacteria
 Compatibility: designed for TetraTec BF 400 / BF 600 / BF 700 internal filter models
 Intended aquarium size: small to medium tanks (as per corresponding filter model capacities)
 Maintenance cycle: recommended periodic replacement during routine filter service
How to use
Turn off and disconnect the filter before accessing the media chamber. Remove the used sponge cartridge and inspect the filter housing for accumulated detritus. Rinse the replacement sponge briefly in aquarium water to remove loose particles and position it correctly in the media compartment following the filter manufacturer’s orientation. Reassemble the filter, refill if necessary, and restart the unit. Avoid using tap water for rinsing biological media to preserve beneficial bacteria.
Usage recommendations
For best results, replace the sponge cartridge according to the filter maintenance schedule or when visible clogging reduces flow. When performing partial cleaning, rinse the sponge in a bucket with aquarium water to retain beneficial bacteria and stagger full replacements to maintain biological stability.
