## Long description

The AquaNatura TN-45217 external aquarium filter delivers mechanical and biological filtration with a rated flow of 800 l/h, designed for freshwater aquariums up to 120 litres. Supplied as a replacement part, this compact canister supports routine maintenance and upgrades to existing filtration systems. Its design helps remove suspended particles and promotes colonisation of beneficial bacteria to stabilise nitrogen compounds and maintain water clarity.
Advantages
The unit combines mechanical and biological media to reduce visible debris and support biological filtration without requiring complex installation. With an 800 l/h flow rate it provides sufficient turnover for tanks up to 120 L while remaining compact in footprint. Being a replacement part, it is compatible with retrofit or repair tasks and helps extend the service life of existing tank equipment. The filter’s sealed canister design reduces evaporation and helps keep piping and connections tidy.
Suitable for (tasks / use cases)
 Routine replacement of a worn or failing external filter on freshwater aquariums up to 120 L
 Upgrading filtration performance for small community tanks and planted aquariums
 Supporting biological stability during fish stocking changes or increased bioload
 Use as a spare unit for maintenance swaps to avoid downtime during cleaning
When it may not be suitable
This filter is intended for freshwater aquariums up to 120 litres; it may not provide adequate turnover or filtration capacity for larger aquariums or heavily stocked systems. It is supplied as a replacement part and may require compatible hoses, connectors or media from the existing system to fit correctly. For marine or reef aquaria that require specialized protein skimming or chemical filtration, a dedicated system may be more appropriate.
Key specifications
 Flow rate: 800 litres per hour
 Recommended aquarium volume: up to 120 litres
 Filtration type: mechanical and biological
 Unit dimensions (approx.): 245 × 115 × 150 mm
 Canister-style external filter with inlet and outlet connections
How to use
Install the filter according to the aquarium’s existing plumbing layout, ensuring inlet and outlet hoses are securely connected and the canister is positioned below tank water level if required by the pump design. Prime the unit or follow the manufacturer’s start-up procedure to remove air and establish steady flow. Load appropriate mechanical and biological media into the media baskets, using coarse sponges or floss for particle removal and ceramic rings or bio-media for bacterial colonisation. Perform regular maintenance by rinsing mechanical media in aquarium water and replacing or replenishing biological media only as needed to preserve beneficial bacteria.
What to consider before purchase
 Confirm physical dimensions and hose connection sizes match your existing setup
 Ensure the 800 l/h flow rate is suitable for your aquarium’s volume and bioload
 Check compatibility of included media with your filtration needs or plan to source additional media
 Verify this unit is intended for freshwater use if you keep marine species
Usage recommendations
To maintain stable water quality, use the AquaNatura TN-45217 with a routine maintenance schedule: clean mechanical media every 2–4 weeks depending on loading and perform partial media checks monthly. When cycling a new filter, allow several weeks for biological media to fully mature before increasing stocking density.
