Powerheads are water pumps of various sizes and capacities which can be completely submerged in water. Powerheads are used in saltwater aquariums to move water around in the tank as well as between the tank and a number of pieces of equipment (i.e. protein skimmers). Powerheads are primarily used to duplicate the water movement (surface waves and surge or swell) in the oceans.
Not all aquarium powerheads are created equal. Although there are only a few units suitable for running wavemakers, there are many that have a lot of lifting power that are suited for use with protein skimmers or as a water pump, while others work best for UGF enhancement, if attachments are included. Most all can be used for generating water movement and circulation in aquariums, but taking the time to compare maintenance requirements, cost, features, and GPH rates will help you make a wise choice.
