## Summary description

AquaNatura replacement bio filter roll TN-45215 designed for use with AquaNatura filter models TN-45197 and TN-45199. Serves as a biological filtration media to support beneficial bacteria growth, improve water clarity and reduce harmful substances in aquariums. Easy to install as a spare part for routine maintenance and filter cartridge replacement.

## Long description

The AquaNatura replacement bio filter roll TN-45215 is a biological filtration media designed for AquaNatura canister filters TN-45197 and TN-45199. It provides a porous surface that encourages colonization by beneficial nitrifying bacteria, contributing to ammonia and nitrite reduction and helping maintain stable aquarium water conditions. The roll is supplied as a spare part for routine maintenance and cartridge replacement and is intended to be easy to fit into the filter compartment.
Advantages
This bio filter roll offers a high-surface-area non-chemical medium that supports natural biological filtration processes. Its structure allows for efficient water flow and bacterial colonization while helping to improve water clarity and reduce harmful nitrogenous compounds. The replacement roll is sized to match the filter models specified and is intended for straightforward installation and periodic replacement as part of regular filter upkeep.
Suitable for
 Freshwater aquariums requiring biological filtration support
 AquaNatura canister filters TN-45197 and TN-45199
 Routine filter maintenance and media replacement
 Environments where gradual establishment of nitrifying bacteria is required
When it may not be suitable
This bio filter roll is not a mechanical polishing pad or an activated carbon chemical adsorbent; it does not remove dissolved organics, heavy metals, or discoloration from water in the way chemical media do. It may not be suitable as the sole solution where immediate chemical removal of toxins or odors is required. Additionally, if your filter model differs from the specified models, fit and performance cannot be guaranteed.
Key specifications
 Function: biological filtration media
 Material type: porous roll suitable for bacterial colonization
 Compatibility: designed for use in AquaNatura filter housings TN-45197 and TN-45199
 Installation form: roll format for trimming or fitting into media chamber
 Maintenance: intended for periodic replacement during regular filter service
How to use
Turn off and disconnect the filter according to the manufacturer’s safety instructions and open the filter unit to access the media chamber. Remove the old bio roll and inspect the chamber for debris. Fit the replacement roll into the designated compartment, trimming to size if necessary to ensure proper water flow and contact area. Reassemble the filter, restart the unit, and monitor water parameters over the following days to allow the bacterial colony to re-establish and stabilize ammonia and nitrite levels.
What to consider before purchase
 Verify that your filter model is TN-45197 or TN-45199 to ensure compatibility
 Consider whether you also need mechanical or chemical media for polishing or odor removal
 Plan for periodic replacement as part of routine aquarium maintenance
 Check the physical dimensions of the media chamber if trimming will be required
Usage recommendations
Use this replacement bio filter roll as part of a multi-stage filtration approach: pair with mechanical pre-filters to remove solids and, if needed, chemical media for targeted contaminant removal. Allow time for beneficial bacteria to re-colonize after installation and test water parameters regularly during the establishment period.
