What we love about this pond is that it requires no connection to mains electric. This pond can be buried absolutely anywhere in the garden and is low-maintenance. The solar pond pump has a lithium battery meaning it can run for up to 8 hours without sun - plus a mains adaptor is included for times that the pump battery needs a boost of energy. The pond pump sits inside the filter drawing towards it dirt and debris but the dirt gets caught in the filter sponges without clogging the pump. The pond kit includes: * PondXpert Tench preformed pond * PondXpert SolarShower 600 pond pump * PondXpert 9v mains adaptor * PondXpert EcoFilter 4000 underwater filter * PondXpert zeolite filter media (5 Litres) * PondXpert black instant waterfall * 2m (6\'6\") x 10mm pond hose * 1 x 10mm clip Note: The preformed pond must be buried in ground. * Saving based on buying pond kit items separately.
