Do I need a pump for my pond?

Yes. Water movement in the pond maintains a healthy, well balanced environment. It also enables you to create an impressive water feature, i.e. fountain nozzles, waterfalls, streams, statuary, etc. The pump recirculates the pond water and insures that oxygen levels remain evenly distributed throughout the pond. Also, the pump will prevent stagnation which can lead to unpleasant odor and prevent mosquitoes from laying eggs on the surface.
