Buying Guide

1. Flow Rate

You need to calculate the required water flow rate for your aquarium. The general rule of thumb is to have a pump flow rate of 5-10 times the aquarium volume. So, if the volume of your tank is 10 gallons, you will need a pump with a flow rate of 50GPH to 100 GPH.

Choosing the best aquarium return pumps that match the volume of your tank is very important. An underpowered pump can prove to be completely ineffective, and an overpowered pump can lead to the water splashing out of the tank. Also, if the water current is powerful, it can stress the small fishes used to live in a calmer environment.

2. AC Return Pumps vs. DC Return Pumps

In recent years, DC pumps have generally been more popular than AC pumps. There are quite a few good reasons for this. First, DC pumps have embedded controller systems. These allow you to either shut off the flow while feeding or make precise changes to the flow rate of the return pump.

Also, DC pumps are generally much more power-efficient than AC pumps. They can also be controlled via a dedicated controller or even wirelessly through mobile devices.

Traditional AC pumps have no embedded control systems and have a fixed flow rate. Therefore, the only way to change the flow rate on these pumps is to install valves in the water flow pipes.

You must be thinking about why people still buy AC pumps when DC pumps are better in almost every aspect. The only reason for this is that AC pumps are less complex and tend to last longer than DC pumps.

3. Submersible vs. In-line

Most commercial return pumps are made to be submerged underwater and hence known as internal or submersible pumps. These are easy to install, and all you need to do is dip the pump in the tank and connect the return pipe to the sump filter.

However, some pump designs require them to be plumbed to the exterior of the aquarium tank. These types of pumps are known as external pumps. These pumps can flow water over longer distances than internal ones and are last longer in saltwater environments.

You need to clean both pump types periodically to remove algae and other waste materials. This requirement is where internal pumps take the lead. Internal pumps are easier to maintain as they can be detached from the aquarium easily without undoing any complex plumbing.

If you want a simple and easy-to-clean pump, you should go with a submersible pump. Indeed, the external pumps generally perform better in saltwater tanks. But some of the inline pumps that we have mentioned in our list are designed to pump salt water just as good as external pumps.

However, the decision of whether you should choose a submersible or an in-line pump depends on your preference, use case, and the design of your aquarium.


It is crucial to pick the best aquarium return pump to ensure your fish’s health and long life. Choosing the wrong pump can not only turn out to be a waste of money but also adversely affect the health of your marine pets.

If you want only the best for your fish, we highly recommend you to go for the Sicce Syndra SDC submersible return pump. It fits all your needs as you can use it both internally and externally. Plus, you can use it on both freshwater and saltwater aquariums.
