What is a Powerhead?

Water Pump
Water Pump

A powerhead is a pump that can be fully submerged in water. It can be used for a variety of purposes, including to drive undergravel filters, increase water circulation, or to pass water through a wet/dry trickle filter or protein skimmer.

Do Saltwater Tanks Need Powerheads?

Saltwater tanks need a lot of water movement and flow to provide fish, invertebrates, LPS corals (Small Polyp Stony Corals), SPS corals (Large Polyp Stony Corals), and aquatic plants with a healthy environment. Powerheads are beneficial in reef aquarium as they prevent dead spots and increase oxygen levels and water circulation.

However, if you have a strong filter that can produce enough flow for the total tank volume, then a powerhead isn’t essential. That being said, many saltwater aquarists use powerheads in their setups even with a good-quality filter for extra water movement.

Many SPS corals and LPS corals need a lot of oxygenation and water movement to survive. In addition, stronger currents help remove gasses that could otherwise affect the health of your fish and corals.

What is the Difference Between a Powerhead and a Wavemaker?

Powerheads for Increased Flow in Aquarium

Aquarium powerheads and wavemakers are often used interchangeably, but they actually work a little differently from one another. Powerheads pump water in a narrow line in one direction, whereas wavemakers replicate ocean waves by shooting water in a back and forth motion to generate a pulsing flow.

Should I Have Both?

It’s not necessary to use both a powerhead or a wavemaker, so if you already own one of these flow tools, you don’t need to purchase the other. However, some aquarists use multiple powerheads or wavemakers in their aquariums to achieve optimal flow rate, especially in large setups with big fish.

Benefits of Using a Powerhead

Water Circulation
Water Circulation

Powerheads and other flow tools are useful in a reef tank as they increase water circulation and oxygenation, both of which are important for promoting good water quality. More water movement means better water quality for your fish and corals.

The consistent water circulation powerheads provide also allow even heat distribution, preventing hot or cold spots in your tank.

Aquarium powerheads prevent stagnant water and help stop detritus and other waste from falling to the bottom of your tank. This helps enhance filtration by making it easier for your filter to remove these particulates to keep your reef aquarium clean and clear.

Using powerheads or circulation pumps in a tank can also prevent algae growth or algae breakouts as many types prefer slow-moving, stagnant waters.

Things to Consider

Below are some things you should consider before purchasing powerheads for a reef tank.


The majority of powerheads aren’t usually too expensive, but high-end devices with multiple features can be quite costly. If you have a nano tank with small fish and no corals, a basic powerhead will usually do the trick.

However, large fish tanks and those containing corals will need at least 2 powerheads, ideally with a high flow, to provide ample water movement and flow.

Flow Rate

Another thing to consider is the flow rate of the powerhead. Powerhead flow rates are calculated using GPH (gallons per hour). As a rule, you should aim to use a powerhead that can turn over at least 10x the volume of your aquarium.

Similar to most saltwater fish, reef tanks that house corals will need a lot of water movement and oxygenation, so powerheads with a high flow rate will be ideal.


Reef Tank
Reef Tank

Powerheads can be used for a wide range of purposes in a reef tank, from driving undergravel filters to increasing water circulation. Think about what you plan on using your powerhead for so you can select a model that suits your needs.

For instance, if you have a large tank with lots of corals, you’ll need at least 2 powerheads that provide a high water flow.


Lastly, you’ll need to consider the size of your powerhead and the volume of your tank. Powerheads can be quite bulky, so if you only have a nano aquarium, you may want to select a model that is both sleek and compact to help it blend it.

Additionally, as mentioned above, make sure the powerheads you use have a suitable flow rate for the size of your aquarium.

Where Should a Powerhead Be Placed in a Saltwater Tank?

You should place your powerhead on the back wall of your reef tank, ideally in the middle or upper region of the aquarium. For a small aquarium, you can get by with a single powerhead.

Large fish tanks, however, will benefit from at least 2 powerheads (1 on each side of the tank) for maximum water circulation and oxygenation.

What Size Powerhead Do I Need?

As a general rule, a powerhead should have a turnover of at least 10x the volume of your reef tank. So, if you have a 100-gallon reef aquarium with no corals, your new powerhead should have a GPH of around 1,000.

Reef Tank VolumePowerhead Flow Rate
10 Gallons100 GPH
20 Gallons200 GPH
40 Gallons400 GPH
50 Gallons500 GPH
75 Gallons750 GPH
100 Gallons1,000 GPH
150 Gallons1,500 GPH
Powerhead Size

Bear in mind that soft corals and LPS corals will benefit from at least a 20 x turnover, whereas SPS corals will require at least 50 x turnover.

What Size Powerhead Do I Need for a 20 Gallon Saltwater Tank?

For a 20-gallon tank, you’ll need a powerhead with a flow rate of at least 200 GPH. However, if you have LPS or soft corals, you’ll need a minimum of 400 GPH.

SPS corals, on the other hand, will require a powerhead with a current flow of 1,000 GPH.
