Powerhead (pump)
An aquarium powerhead is a water pump completely submerged into an aquarium to circulate water; usually this is used to create flow throughout the tank. For example a single powerhead could be used at one end of a freshwater aquarium to simulate a laminar river current, or multiple powerheads can be positioned throughout the aquarium to create more turbulent flow. A switching or variable-voltage system (also known as a "wavemaker") is commonly used in reef aquaria to more closely simulate the movement of ocean water.〔http://saltaquarium.about.com/cs/bcorsettingup/a/aa121597waves.htm〕 Water circulation is vital to proper biological filtration of most saltwater aquaria (particularly those using the Berlin Method), and is useful in freshwater aquaria for allowing free-swimming fish adequate exercise.〔http://www.onlineaquariumstore.com/acatalog/Aquarium_Powerheads.html〕
