A DC return pump is a type of water pump that is used in marine aquariums to circulate water through the sump and back into the display tank. DC return pumps are becoming increasingly popular because they offer several advantages over traditional AC pumps. For instance, they are more energy-efficient, quieter, and can be controlled more precisely.
There are many different types of DC return pumps available on the market, each with its own unique features and specifications. Some popular brands include Sicce, Innovative Marine, and Aquarium Station.
When choosing a DC return pump for your marine aquarium, you should consider factors such as the size of your tank, the flow rate you require, and your budget. You can also choose between submersible and external DC return pumps depending on your setup
