This is the best value system for large ponds up to 20,000 litres (4,400 gallons). As it is a pressurised system it allows the option of running the water from the filter to the top of a waterfall. The pump included in this set handles solids up to 6mm and features a new \'ECO\' motor with low running costs, while the filter incorporates a handle to redirect flow from the usual flow to backwash/clean. Thanks to the backwash you can clean your sponges without switching off your pond pump - brilliant! This set contains the following components (please click links below for more information): • PondXpert UltraFlow 12000 pond pump • PondXpert EasyFilter 30000 pressure filter • 5m (16\') x 25mm (1\") hose • 4 x 25mm (1\") clips * Saving based on price of buying components individually.
