Two other advantages to using powerheads in place of circulation pumps is that they are more efficent in terms of electricty drawn and add less heat to the water. Something like a submersible Danner Mag 7 pump will feel noticably warm to the touch and draws 65W. While a Hydor Koralia Evolution 750 will produce roughly the same amount of flow for only 4.5W
