## Long description

MHK Biostone filter insert is a preformed replacement media cartridge designed for aquarium filtration. The cartridge combines porous structure and mechanical trapping to remove suspended debris while providing surface area for colonization of nitrifying and heterotrophic bacteria. It is intended for routine media replacement in home aquaria to help maintain water clarity and support biological filtration processes.
Advantages
The Biostone design delivers both mechanical and biological filtration in a single pre-shaped unit, simplifying media handling and replacement. Its porous matrix promotes stable colonization of beneficial bacteria, which aids in reducing ammonia and nitrite levels. The cartridge is ready to install without cutting or shaping, reducing maintenance time and minimizing disturbance to the filter compartment.
Suitable for
 Internal and hang-on filters that accept preformed cartridges of compatible size
 Freshwater community and planted aquaria requiring routine biological support
 Replacement during scheduled filter maintenance to restore mechanical and biological performance
Key specifications
 Media type: porous Biostone matrix providing mechanical and biological filtration
 Form factor: preformed cartridge for drop-in installation
 Function: traps suspended particles and supplies surface area for beneficial bacteria
 Recommended use: routine replacement to maintain filtration efficiency and water clarity
 Compatibility: for aquarium filters designed to accept cartridge-style media
How to use
Shut off the filter and remove the existing cartridge according to the filter manufacturer's instructions. Rinse the new Biostone cartridge briefly in aquarium water to remove any loose dust, then insert it into the filter compartment in the same orientation as the original media. Restart the filter and monitor flow; bacteria colonization will re-establish during normal operation. Replace at regular intervals or when mechanical clogging reduces flow, following the maintenance schedule appropriate for your aquarium bioload.
Usage recommendations
For consistent biological stability, replace the cartridge as part of scheduled maintenance rather than all media at once. When changing multiple media units, stagger replacements over several days to preserve established bacterial populations. Use rinse water from water changes for initial rinsing to avoid chlorinated tap water that can harm beneficial bacteria.
