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.

What to Look for in an Aquarium Powerhead

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 under gravel filter 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.​

Flow Rates

On average, you'll want the water in your aquarium to turn over 6 to 10 times per hour. To ensure that your powerhead will do this, calculate the flow rate of your aquarium. Once you have your flow rate, you can look for a powerhead that will generate enough flow to keep your aquarium running smoothly.

Size and Placement

Size isn't as important to powerheads as placement is. You'll want to position your powerhead to move the water towards the front of the aquarium. This will allow the debris circulated by the water to flow into your aquarium's filter. Many aquarists also prefer to buy a couple of smaller powerheads to mount on opposite ends of their tank rather than just one. This helps to prevent stagnant water and dead spots from forming. However, if you have a small aquarium you may not need to buy multiple powerheads.


Some powerheads don't have the capability to work well with other devices found in an aquarium, such as a protein skimmer or wavemaker. The on/off function of a wavemaker can put excess strain on a powerhead and it won't work as it should. Make sure to find a powerhead that will function properly with any additional devices.
