Product Description

Introducing the Fluval U3 Underwater Filter. This product provides complete and efficient 3-stage filtration, including BioMax biological filtering, to create superior aquarium water quality. The filter provides the option of setting the flow output in 3 different positions, a key benchmark in underwater filtration. The adjustable 3-way flow control feature lets you position the water flow output to meet your specific needs. The Top Output setting provides maximum circulation and oxygenation, the Integrated Spray Bar setting provides a gentle, even flow for planted aquariums, and the Bottom Output setting is for deepwater agitation. The filter also has a convenient flip-top lid that allows quick and easy access to the filter cartridge for maintenance or replacement.
