This pond kit requires no mains electricity to run. It uses a solar pond pump with lithium battery back-up and an underwater EcoFilter to clean the pond water. The pond pump includes LED lights which automatically illuminate at dusk. A 9V mains charger is also included for periods when sunlight is low, which is vital should you keep any fish in your eco-pond as water movement stimulates oxygen development. This 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) Note: The preformed pond must be buried in ground. * Saving based on buying components separately.
