## Summary description

AquaNatura external aquarium filter TN-45199 delivers 800 l/h flow suitable for aquariums up to 120 L. It includes a bio-filter roll for biological filtration and an integrated surface skimmer to remove film and debris. Designed for continuous recirculation, it supports mechanical, biological filtration and improves water clarity for freshwater setups.

## Long description

The AquaNatura TN-45199 external aquarium filter delivers a rated flow of 800 l/h and is designed for freshwater aquariums up to 120 litres. This canister-style filter combines mechanical and biological filtration in a compact housing and includes a replaceable bio-filter roll plus an integrated surface skimmer to remove surface film and floating debris. The unit is intended for continuous recirculation and provides clearer water and improved oxygen exchange when installed and maintained according to the manufacturer's instructions.
Advantages
The AquaNatura filter provides a combination of mechanical pre-filtration and biological media in one compact unit, reducing suspended particles and supporting nitrifying bacteria colonisation. An included bio-filter roll simplifies media replacement and maintenance, while the built-in surface skimmer targets surface contaminants that reduce light penetration and gas exchange. The 800 l/h rated flow ensures sufficient turnover for aquariums up to 120 L, and the design aims to minimise vibration and noise during operation.
Suitable for
Freshwater aquariums up to 120 litres requiring steady mechanical and biological filtration
Tanks with light surface film or floating debris that benefit from surface skimming
Hobbyists seeking a compact external canister filter with easy-to-replace filter roll
When it may not be suitable
This filter is sized for aquariums up to 120 L; it may be undersized for larger or heavily stocked tanks where higher turnover or additional media capacity is required. It is designed for freshwater use—saltwater reef systems or tanks requiring advanced chemical filtration may demand different media types or multiple filtration stages not provided as standard.
Key specifications
Rated flow: 800 litres per hour
Recommended aquarium volume: up to 120 litres
Filtration stages: mechanical pre-filtering with bio-filter roll and biological filtration
Included feature: integrated surface skimmer for surface film removal
Suitable for continuous recirculation in freshwater setups
How to use
Install the external filter according to the supplied instructions, placing the canister below the aquarium and connecting intake and outflow hoses securely. Prime the unit as directed to remove air and start the pump; ensure the surface skimmer intake is positioned to capture surface film without creating excessive surface agitation. Replace or rinse the bio-filter roll at regular intervals depending on stocking levels and feed rates; avoid cleaning all biological media at once to preserve beneficial bacteria. Check hose connections and seals periodically to prevent leaks.
What to consider before purchase
Confirm your aquarium volume does not exceed the recommended 120 L capacity for effective filtration
Consider stocking density and bioload—heavily stocked tanks may require higher flow or extra media
Verify suitability for freshwater aquariums; saltwater or reef-specific requirements may need different equipment
Usage recommendations
For stable water quality, run the filter continuously and perform regular partial water changes. Inspect and replace the bio-filter roll as needed while maintaining some established biological media to preserve nitrifying bacteria. Position the skimmer intake to remove surface film without disturbing beneficial surface flow patterns.
