## Long description

Tetra A1-607699 is a replacement biological filter foam pad designed for aquarium filtration. Made from porous foam, this media captures suspended particles and provides a high-surface-area substrate for beneficial nitrifying bacteria. It fits as a cartridge insert or foam block in compatible Tetra filter systems and helps maintain water clarity and biological stability in freshwater aquariums.
Advantages
The foam pad combines mechanical and biological filtration in a single element, trapping debris while encouraging colonization by nitrifying bacteria that convert ammonia and nitrite. Its open-cell structure supports water flow and oxygen exchange, promoting effective biological activity. The durable foam can be rinsed and reused multiple times, reducing the frequency of full media replacement and simplifying routine maintenance.
Suitable for
Freshwater aquarium filtration in compatible Tetra canister or internal filters
Supporting biological filtration in established aquaria with fish and plants
Replacement of worn or clogged foam pads in routine filter maintenance
Key specifications
Material: open-cell porous foam suitable for beneficial bacteria colonization
Function: combined mechanical debris trapping and biological media
Form: foam pad designed for insertion into compatible filter cartridges or housings
Compatibility: intended for use with compatible Tetra filter systems for freshwater aquariums
Maintenance: washable for reuse; replace when structurally degraded or persistently clogged
How to use
Turn off and unplug the filter before removing the old foam pad. Remove the existing media according to the filter manufacturer's instructions and insert the replacement foam pad into the cartridge slot or filter chamber in the same orientation. Reassemble the filter, restore power, and check for proper water flow. During the initial days after installation, monitor water parameters as the biological community re-establishes. Rinse the foam pad gently in dechlorinated aquarium water during routine maintenance to remove accumulated debris without eliminating beneficial bacteria.
Usage recommendations
Rinse the foam pad in tank water rather than tap water to preserve nitrifying bacteria. Replace the pad if it becomes torn, permanently compressed, or cannot be cleaned effectively. For optimal biological performance combine with appropriate mechanical and chemical filtration stages as recommended for your specific Tetra filter model.
