This unique system takes an all-in-one pump and matches it up with a box filter, which results in clear water for any pond of up to 2,500 litres (500 gallons). You can essentially think of this as a pump with a built in UVC pushing dirty water up to a box filter where any small debris can be collected. The pump has a flow rate of 1,000lph and comes fitted with a powerful 13w UVC, while the filter box includes three layers of filter media. This set contains the following components (please click links below for more information): • PondXpert TripleAction 3000 pond pump • Fish Mate 5000 box filter • 5m (16\') x 25mm (1\") hose • 2 x 25mm (1\") clips * Saving made when compared to buying items separately. NOT SUITABLE FOR KOI PONDS. NOTE: UVC bulb included.
