A marine tank’s circulation is like the body’s circulatory system. It is essential to keep water moving through the system, just as it is important to keep blood flowing through the body. Like the body’s circulatory system, failure to move water at the proper rate can result in poor system health and even death. In the body, the heart is responsible for pumping the blood. In the aquarium, it is the return pump. It’s necessary to calculate how much work this pump will be required to do based on the type and configuration of the plumbing. This article looks at how to calculate necessary return pump back-pressure or head pressure so that the appropriate circulation can be achieved.

In the sample system discussed in this series–a 135-gallon tank connected to a sump and several biotope-specific tanks–the water flows to the sump via an overflow and is then pumped back to the tank via a return pump. This is known as an "open system." It relies on two primary mechanisms to keep the water flowing: 1) gravity moves the water from the tank to the sump, and 2) the return pump pumps the water back to the tank.
