What are Fluval U Series Filters? Fluval U Series Filters provide easy, convenient filtration, and have the capacity to independently filter aquariums up to a 240 litre capacity as the primary filter or act as a supplementary filter in a larger aquarium. These internal, underwater filters feature a three-stage filter with Biomax for superior aquarium water quality. The filters come in a range of sizes, to suit a variety of aquarium setups. What are the benefits of the Fluval U Series Filters? The Fluval U Series Filters have a range of features including: Flip-top access – Access via a convenient flip-top lid to quickly and easily reach in and change the filter cartridge. Custom flow patterns – Fluval U series filters provide the option of setting the flow output in 3 different positions, a key benchmark in underwater filtration. The Adjustable 3-Way Flow Control feature (U2, U3 and U4 models) lets you position the water flow output to meet your specific needs. A setting for every need – 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. How long does a Fluval filter last? The Fluval U filter range can be used in freshwater, marine or reptile environments and all come with a 3-year guarantee. However, Fluval filters can last much longer if well maintained and cared for with regularly replaced media. You can purchase replacement media for these filters, which are quick and easy to change over.
