Return Pump Rundown: What You Need to Know


Today we are going to go over the different types of return pumps to help you choose the right pump for your aquarium.

Water pumps are the backbone of aquarium filtration. The tank is cleaned as the pump moves water through your filtration system. Pumps also help ensure proper gas exchange and healthy levels of dissolved oxygen.

When building an aquarium with a sump or using an all-in-one aquarium, you will often hear the term "return pump." This refers to the main pump that returns water from the sump/filter back into your display tank. There are a wide variety of water pumps available to suit every aquarium application.

Pumps are generally grouped into two categories: submersible pumps (which means the entire pump is submersed in water) and external pumps (which means the pump is mounted outside of the water). Keep in mind that many pumps fall into both categories, so do not let this confuse you. More and more pumps are being sealed so that they are safe for both submersed and dry applications.
