Return Pumps & Water Flow
A powerhead is a submersible aquarium pump with low energy consumption that circulates aquarium water. Freshwater aquariums need 3-5x water volume movement per hour; reef tanks sometimes have more than 50x. An aquarium circulation pump oxygenates water movement and keeps waste from settling.
Tanks with external filtration need an aquarium water pump. A submersible return pump sits in the sump and is easier to plumb. An external aquarium pump transfers less heat and can be larger. DC return pump setups are quiet, low energy, and often controllable, while also working submerged or external.
A small aquarium pump can feed a reactor, sterilizer, or other equipment. A protein skimmer pump produces foam to remove organic waste.
