STABILUS aquarium internal filter TN-44580, dual-chamber, 182×105×80 mm

STABILUS aquarium internal filter TN-44580 is a compact dual-chamber unit designed for small to medium freshwater aquariums. The internal filter measures 182×105×80 mm and mounts inside the tank to provide steady water circulation, mechanical debris capture and support for biological filtration media. The two chambers separate coarse mechanical filtration from biological media, helping to maintain clearer water and stable biological conditions in routine aquarium maintenance.

Advantages

The dual-chamber design provides distinct mechanical and biological filtration stages inside a single compact housing, reducing the need for external equipment. Its internal mounting ensures direct water intake and return within the aquarium, improving circulation while keeping the device discreet. The unit’s size makes it suitable for confined aquarium spaces without compromising filtration capacity, and the straightforward construction simplifies installation, cleaning and media replacement.

Suitable for

• Small to medium freshwater aquariums
• Community fish tanks with low to moderate bioload
• Planted aquariums requiring gentle circulation
• Maintenance setups where internal mounting is preferred

Key specifications

• Type: Internal aquarium filter with dual chambers for mechanical and biological filtration
• Dimensions: 182 × 105 × 80 mm
• Installation: Internal, mounts inside the aquarium
• Filtration stages: Separate compartments for debris capture and biological media
• Suitability: Designed for freshwater use

How to use

Place the STABILUS TN-44580 inside the aquarium on a flat surface or secure it to the glass following the manufacturer's mounting method. Fill the mechanical chamber with appropriate sponge or foam media and the biological chamber with ceramic rings or other biological media as preferred. Connect the filter to a compatible power source, confirm correct water flow and adjust position so intake and outflow promote gentle circulation without strong currents that could disturb livestock or plants. Regularly inspect and rinse mechanical media to remove accumulated debris and replace or refresh biological media as part of routine maintenance.

Usage recommendations

For consistent performance, perform weekly checks during the first month after installation to confirm flow and media condition. Clean mechanical filter media using aquarium water to preserve beneficial bacteria and avoid complete sterilization of biological media. Use the unit in freshwater tanks only and monitor water parameters after installation or media changes to maintain stable conditions for fish and plants.
