Fluval U3 Underwater Filter

Internal Filters are an excellent option for small to medium sized aquariums. They are simple and easy to set up, they sit just inside the aquarium itself meaning they can be easily installed into any fish tank, with no troublesome pipes and hoses. They will also work well as a powerhead for water circulation, with the added bonus of the extra filtration. This filter has a 3 stage filtration process, it assists with removal of fine particles, chemicals and odours. The convenient quick flip top allows easy access for maintenance and media changes. Featuring an adjustable flow, this filter lets you position the water flow output to meet your specific needs whilst the integrated spray bar provides a gentle, even flow for planted aquariums. Position horizontally for shallow tanks, larger tanks with low water levels, or to create a decorative waterfall feature. Position vertically against aquarium wall to create currents or customized flow patterns. U series underwater filters offer superior water purification, movement and aeration capabilities and have been designed for use in both fresh and saltwater applications.
