The 12 Best Aquarium Return Pumps

The appropriate return pump is a crucial component of a properly working aquarium, and the ideal one for your needs will depend on a number of criteria.

You must consider the size of your aquarium, the amount of fish in it, and the species of fish you have; certain fish are sensitive to too much movement, while others require it.

The tides cause regular water movement through and around a natural coral reef. This action assists the reef in obtaining necessary nutrients while also washing away trash.

This movement is also required to deliver oxygenated water to your fish and to circulate the water through the filtration system.

Finding the appropriate unit for your fish tank can be challenging, but don't fret! BestForPets (bestforpets.org) has done the legwork for you and compiled this list of the best aquarium return pumps to assist you to locate the product that best meets your specific needs.

The Jebao DCP Sine Wave return pump is our top recommendation for aquarium return pumps. The Jebao is a small, compact, and powerful machine. But don’t be fooled by its modest size; it packs a powerful punch.

Due to its sine wave technology, the pump operates quietly and includes a memory recall feature for when the power goes out. This is a wonderful feature, as you will not need to alter the settings after a power outage.

The pump has a flow rate of 1,710 GPH (gallons per hour) and a design that makes it about 50 percent more energy efficient than its predecessor.

It also has a wall-mountable controller, allowing you to create a personalized flow rate according to your preferences. Copper-free components render the machine safe for use with water and rustproof.

Several users have reported that the pump leaks when used outside the water, therefore there may be an issue with seal quality control. Moreover, the flow rate is subject to fluctuation, making it difficult to monitor the overflow level of your tank.

It offers a respectable 1052 GPH flow rate, making it excellent for small to medium-sized aquariums, and its detachable construction makes it simple to clean.

Users note that this pump’s flow rate is not as powerful as advertised, and it regularly underperforms at high settings.

Additionally, barbed hose connections are included for simple setup and installation, and this pump is very silent. This is an excellent feature for bedroom and living room aquariums.

This pump is larger than the majority of the other pumps on this page, which is particularly essential if you intend to use it submerged in a tiny aquarium.

What to Consider when Buying Aquarium Return Pumps?

A high-quality return pump is vital for the health and functionality of an aquarium. It permits all the water entering your aquarium to first pass through the filtration system, ensuring that only clean, filtered water enters your aquarium and aiding in oxygenating the water.

But how can you ensure that you’re selecting the right pump for your tank? There are several crucial aspects to consider.

Internal or external?

Even though many pumps on the market can perform both functions, return pumps normally fall into two categories: submersible and exterior.

A submersible pump can be completely submerged and function in water (often both freshwater and saltwater), whereas an external pump can only be utilized outside of the tank.

Both of these alternatives have advantages and limitations, which is why hybrid units are so prevalent.

Submersible pumps are typically quieter and easier to install and maintain, but if they run hot, they can have a significant impact on the temperature of the water in your tank.

External pumps require regular maintenance and are more difficult to install. However, they are typically more powerful, have higher flow rates, do not transfer more heat to the aquarium’s water, and stay longer.

Volume

The volume capacity of your aquarium is also an important thing to consider. If you purchase a pump that is too tiny for your aquarium’s water capacity, the water in your tank will not be filtered effectively.

This will eventually lead to an unhealthy environment for your fish, as well as a possible pump motor failure. If you have a pump that is too big for your aquarium, it can easily cause the tank or sump to overflow.

In addition, larger pumps are more costly, so purchasing one that is too large is a waste of money.

AC vs. DC Pumps

AC pumps have always been the standard for aquariums, requiring little more than connecting them to the wall. Recently, DC pumps have gained popularity, as they often come with a controller that allows you to customize the speed.

You can modify the flow rate of your pump with the push of a button, which is a major benefit if you have multiple species of fish.

In the event of a power outage, these pumps can be equipped with backup batteries, and more complex models can even be changed remotely via smartphone apps. DC pumps cost more than AC pumps.

Noise

Since aquariums are typically situated in bedrooms or living rooms, the last thing you (and your fish) want is a noisy pump.

The noise can convey detrimental vibrations throughout your aquarium, causing distress to any organisms that reside there.

Some pumps are noisier than others, even though correct installation can decrease the noise of many pumps.

As long as they do not contact the tank’s walls or any installed pipes or rock features, submersible pumps are typically more quiet.
