The SwimSkim 25 enables the quick and easy removal of floating debris from the pond surface. The three float chambers suspend the pump at water surface level and because it floats, it automatically adjusts to changes in water level. The water is sucked down through the strainer by the 2500 litre per hour pump (550 GPH) in the SwimSkim 25 and pushes water out through the built-in oxygenator, aerating the water as it works. The strainer will collect large debris such as leaves, but also includes a fine sponge filter to catch finer waste. The SwimSkim 25 is designed for ponds up to 25m Sq (e.g. a pond 5m x 5m). The 40w motors are supplied with 10m of cable and have a 2 year guarantee. Dimensions of the 25: Length 332mm x Width 297mm x Height 250mm.
