An effective way to remove surface debris from your pond. Designed to be placed so that the top rim sits on the water's surface. The lower tray at the base can be filled with pebbles, etc. to weigh it down to prevent the skimmer floating or being knocked over. The skimmer is powered by a pump not included which is attached to the stepped hosetail. The Bermuda surface skimmer is ideally powered by either a Bermuda Filterforce Filter Pump 4500 BER0615 or a Bermuda Filterforce Duo Filter Pump 4500 BER0771. Dimensions 35cm x 86.5cm. 1 Year Guarantee.
