Fluval U3 Underwater Filter for Aquariums

A Complete Set Of Specifications

Use this filter as the primary option for smaller aquariums, or as a supplementary choice for larger tanks.

Its sleek design includes an easy-to-grip water control panel and a redesigned media cartridge, which effectively traps more debris.

A convenient flip-top lid makes it simple to access the filter cartridge for maintenance or replacement.

Position the filter horizontally for shallow tanks, larger tanks with low water levels, or to create a decorative waterfall feature. You can also place it vertically against the aquarium wall to generate currents or customize flow patterns.

This filter is perfect for freshwater, saltwater, and reptile environments up to 40 gallons.
