## Summary description

Exo Terra BioMax filter cartridge is a replacement biological media designed for AC20 and AC30 aquarium filters. It provides surface area for beneficial bacteria colonization to support biological filtration, helping break down ammonia and nitrite. Intended for routine maintenance and media replacement in compatible Exo Terra filter housings to maintain water quality in freshwater and planted aquariums.

## Long description

The Exo Terra BioMax filter cartridge for AC20/AC30 aquarium filters is a biological media replacement designed to support efficient biological filtration in freshwater and planted aquariums. It provides a porous surface area that encourages colonization by nitrifying bacteria, promoting the conversion of ammonia and nitrite into less harmful compounds. The cartridge is intended as a direct media replacement for compatible Exo Terra filter housings and for routine maintenance to help maintain stable water quality.
Advantages
The BioMax cartridge offers a high surface-area structure that supports fast bacterial colonization, improving the aquarium's capacity to process nitrogenous waste. Its form factor is sized to fit AC20 and AC30 filter models, making installation and replacement straightforward. The media's porous composition ensures good water flow and contact with beneficial bacteria, aiding consistent biological filtration without altering mechanical filtration performance.
Suitable for
Freshwater aquariums where biological filtration is required
Planted tanks that need stable nitrogen cycling
Routine maintenance and scheduled media replacement in compatible filter units
Key specifications
Media type: porous biological filtration material
Designed dimensions: compatible with Exo Terra AC20 and AC30 filter cartridges
Function: provides surface area for beneficial bacterial colonization
Flow characteristic: allows sufficient water throughput for biological activity
How to use
Turn off and unplug the filter before performing maintenance. Open the filter housing and remove the used cartridge. Rinse the filter housing and, if necessary, gently rinse the new BioMax cartridge with aquarium water to remove any loose particles; avoid using tap water or disinfectants that can kill beneficial bacteria. Insert the BioMax cartridge into the filter housing in the same orientation as the previous media, reassemble the filter, and restart the unit. Follow the aquarium's maintenance schedule to determine appropriate replacement intervals.
Usage recommendations
For best results, replace the BioMax cartridge on a schedule consistent with your aquarium's bioload and maintenance routine. When cycling a new tank, consider retaining a portion of established biological media from an existing system to seed beneficial bacteria. Monitor ammonia and nitrite levels after replacement and avoid replacing all biological media at once in heavily stocked aquariums to prevent disruption of the nitrogen cycle.
