## Summary description

AquaNatura filter ball cartridge TN-45169 is a replacement aquarium filtration element with a sponge insert and 26 mm outer diameter. Made from PVC and PU materials, it fits compatible pump or filter inlets to provide mechanical filtration and biological surface area. Suitable for freshwater and marine tanks as routine cartridge replacement or for improved particulate capture.

## Long description

AquaNatura filter ball cartridge TN-45169 with sponge insert is a replacement filtration element designed for aquarium pumps and filters with a 26 mm inlet. Constructed from PVC and polyurethane (PU), the cartridge provides mechanical trapping of suspended particles while the sponge surface increases available area for beneficial bacteria colonisation. The compact 26 mm diameter design makes it suitable for many small to medium internal filter housings and pump inlets, and it can be used in both freshwater and marine aquaria as part of routine maintenance or during targeted cleaning cycles.
Advantages
The cartridge combines a rigid PVC outer body with a porous PU sponge insert to balance durability and filtration efficiency. Its 26 mm diameter allows straightforward fitting into compatible filter inlets, and the sponge insert enhances particulate capture and offers additional biological surface area without significantly restricting flow. Materials are suitable for aquarium use and are easy to rinse for reuse in short-term service intervals.
Suitable for
Replacement filter element for internal aquarium filters and small pumps with 26 mm inlet
Mechanical filtration to remove debris and suspended particles in freshwater tanks
Biological surface support in marine aquaria when used alongside biological media
Routine cartridge replacement during maintenance cycles
Key specifications
Outer diameter: 26 mm
Body material: PVC
Insert material: PU sponge
Function: Mechanical filtration and biological surface area
Compatible environments: Freshwater and marine aquaria
How to use
Turn off the pump or filter before removing the existing cartridge. Remove the filter housing or inlet cover, extract the worn cartridge and insert the AquaNatura filter ball cartridge with the sponge insert so that it seats securely in the inlet. Reassemble the housing or cover and restart the pump or filter, checking for normal flow and absence of leaks. For initial installations, rinse the cartridge briefly in dechlorinated water to remove manufacturing residues. Replace or clean the cartridge according to tank bioload and manufacturer maintenance intervals.
Usage recommendations
For best results, inspect the cartridge weekly during the first month after installation to assess particulate load. Rinse the sponge gently in tank water when clogged; replace the cartridge when structural wear or persistent flow reduction occurs. Use as part of a multi-stage filtration setup if increased biological filtration or finer mechanical removal is required.
