The Aquascape Pond Powerhead is designed to create water movement and eliminate stagnant areas in ponds and water gardens, providing circulation, surface agitation, and aeration. This standalone recirculating pump does not require any pipe or plumbing, simply set the powerhead directly in the pond or disguise it into the pond using rocks or other materials. The energy-efficient, low-voltage motor can be powered by a standard outdoor, 12-volt transformer (not included).
