This pump has enough uses to drive your water year-round. It is durable and useful enough to become a vital part of your aquarium and pond tool-box for years to come! Ideal for aerating large aquariums or ponds, improving fish health through improved oxygenation, powering a skimmer, or keeping outdoor ponds from freezing over completely. Durable design holds up well to the pounding of the outdoors, while quiet operation allows it to blend well into your aquarium setup or backyard. Includes a 6 ft. power cord.
