Product Description:
Rolf C. Hagen presents its Fluval U internal filters. Designed to be silent and efficient, the filters are ideal for situations where aquarists do not desire to use external filtration, the company reports. Intended for use in either freshwater or marine aquariums, terrariums and turtle tanks, the U series features various sizes, from the smallest, the U1, to the U4, which is the largest filter in the line. Each filter features mechanical, chemical and biological filtration capabilities, and the submerged design allows users to create currents within aquaria, the company reported.
