Fluval U3 Submersible Filter, for aquariums from 90 to 150 L (24 to 40 US gal)

The Fluval U3 submersible filter provides complete and effective three-stage filtration and uses BIOMAX filter media for exceptional water quality.

The U3 filter includes many practical and versatile features that make this device essential for freshwater or saltwater aquariums, as well as for terrariums.

Featuring three water outlet position settings, the U3 filter is a benchmark in submersible filtration systems. The adjustable three-way flow regulator allows the water outlet to be positioned to meet your specific needs.

The top outlet allows for maximum circulation and oxygenation, the integrated diffuser tube provides a constant and gentle flow for planted aquariums, and the bottom outlet creates deep water agitation.

The FlipTop lid allows easy and quick access to the filter blocks during maintenance. Furthermore, the filter can be fixed vertically against the wall of an aquarium to create custom currents, horizontally for shallow pools, or to create decorative waterfalls.

The U3 filter includes two foam blocks, two polyester/carbon cartridges, and BIOMAX biological cylinders. This filter is suitable for aquariums with a capacity of 90 to 150 L (24 to 40 US gal).
