Fluval U4 Internal Filter
Suitable for tanks up to 240 litres.
Fluval have been one of the leading brands in filtration for many years and have built a great reputation for producing easy to use, efficient, quiet and reliable products. With a 3 year warranty the U series filters are no exception.
With a flow rate of 1000 litres per hour, the Fluval U4 is a great option for aquariums up to 240L.
First the water passes through the sponge pads which remove large particles.
Next it passes through a fine pad which polishes the water before passing it through a carbon pad which further clears the water and removes any chemical contaminants,
The final stage is the biological media which is contained in the centre of the filter. This chamber contains Fluval Biomax which provides a great home for large amounts of beneficial bacteria.
The clean, safe water is then pumped back into your aquarium through your choice of outlets at a rate that you can control.
There is a 3 way flow control valve mounted on the top for easy access. This can be used to direct flow through the top outlet to disturb the surface of the water, through the centre spray bar to provide a more gentle flow or through the bottom outlet to provide water movement across the substrate.
The filter can be easily removed from the bracket eliminating the need to unstick the suction cups when maintenance is required.
Access to the filter sponges and media is made incredibly simple thanks to the clever flip top lid design, the motor being positioned at the bottom of the unit and the tilt brackets.
You can actually change the media without removing the filter from the aquarium. Simply tilt it forward, open the lid and slide out the sponges and media cartridge.
The unit can be positioned either vertically or horizontally.
