The market is rife with pumps with many differences in size, pumping capacity, intake suction, and even power draw. Newer pumps on the market even have a slow-start feature so as to not suddenly blast water when you turn it on.

In choosing the right pump, you will want to make sure that you first pick the correct pump capacity. Pump capacity is typically denoted by a rating in liters per hour, or gallons per hour. These numbers typically describe the pump capacity in a zero-head or no-pressure situation. When you are putting the pump in your sump and pumping up to your display, this will affect the flow rate! Make sure to view the capacity-to-head graphs to make sure that at your delivery height, it meets your needs.

Buying Guide

DC pumps have hit the market recently for aquatics that offer a way to control the output of the pump by pressing some buttons on a controller instead of turning a physical valve.

They tend to also have slow-start behavior which is nice so that when the pump starts it doesn't immediately go to max and blow water out. This is particularly useful when your display tank's water has drained below your return and now it needs to fill back up for your return to be submersed. With a slow-start, the water will slowly rise and then go to max, whereas with a standard AC pump, the pump will start at full power, which may splash a lot of water!
