Fluval Fluval U4 Filter

Fluval U Series Filters provide easy, convenient filtration, and have the capacity to independently filter aquariums up to a 240 Litre capacity.

These internal, underwater filters feature a three stage filter with Biomax for superior water quality. They have flip top access to quickly and easily reach and change the filter cartridge, making them one of the most convenient ranges around.

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. 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 deep water agitation.

The Fluval U filter range can be used in fresh water, marine or reptile environments and all come with a 3 year guarantee.
