## Summary description

Replacement bio filter roll for AquaNatura aquarium filters TN-45195 and TN-45196 (MPN TN-45214). Designed as a biological filtration media to trap debris and support beneficial bacteria growth. Suitable for routine maintenance and filter cartridge replacement to maintain water clarity and stable aquarium biological filtration.

## Long description

Replacement bio filter roll designed for AquaNatura aquarium filters TN-45195 and TN-45196. This biological filtration media is intended to trap suspended debris while providing a large surface area for beneficial nitrifying bacteria to colonize, supporting stable biological filtration and clearer water between maintenance intervals. The roll is sized and shaped to fit the specified AquaNatura filter housings and is intended for routine cartridge replacement as part of regular aquarium care.
Advantages
The bio filter roll combines mechanical and biological filtration in a single media: it captures particulate waste while offering porous fiber structure for bacterial growth. It is pre-cut to the dimensions used by compatible AquaNatura filters to ensure a snug fit and even water flow across the media. Using a dedicated biological roll helps maintain ammonia and nitrite conversion rates by preserving established bacterial colonies when cartridges are changed, and it can reduce the frequency of deeper tank maintenance.
Suitable for
 AquaNatura TN-45195 and TN-45196 internal cartridge filter units
 Freshwater and lightly stocked community aquariums requiring biological filtration support
 Regular filter maintenance cycles and cartridge replacement
When it may not be suitable
This bio filter roll is not designed to provide chemical filtration (for example, removal of dissolved organics, odors, or medications). Aquariums with heavy bioload, marine systems, or setups that require specialized media (such as activated carbon, phosphate removers, or live rock) may need additional or different filtration components. If your filter model differs from the listed compatible units, verify fit and flow characteristics before purchase.
Key specifications
 Function: combined mechanical and biological filtration media
 Material type: porous fiber roll suitable for bacterial colonization
 Form factor: pre-cut roll sized for compatible AquaNatura cartridge housings
 Primary purpose: trap debris and support nitrifying bacteria
How to use
Turn off and disconnect the filter following the manufacturer's safety instructions before performing maintenance. Open the filter housing, remove the old cartridge or media, and inspect internal compartments for debris. Insert the replacement bio filter roll into the designated cartridge slot ensuring correct orientation and full contact with flow paths so water is forced through the media. Reassemble the unit, reconnect, and restart the filter. Monitor water parameters after replacement; establishing a stable bacterial population can take several days, so avoid extensive chemical treatments immediately after a media change.
What to consider before purchase
 Confirm physical compatibility with your AquaNatura TN-45195 or TN-45196 filter model.
 Decide whether additional chemical or mechanical media will be required for your aquarium's needs.
 Plan replacement frequency according to stocking levels and water quality: biological rolls generally need periodic rinsing or replacement during routine maintenance.
Usage recommendations
For stable biological filtration, stagger full media replacements when possible: replace one cartridge at a time or rinse rather than fully replace established media to preserve beneficial bacteria. Regularly test ammonia and nitrite after changing media to confirm biological filtration remains effective.
