Mind you, this is a most basic overview of how this works, and is assuming a few important things, such as placement of the return nozzles.
Say for example, you want to run your return nozzles to flow at the middle of your display. You set it up and all works well. Then the power goes out. Here is where it becomes important to know how much your display can drain back into the sump. Gravity! If your return nozzles are say halfway down in the display tank, gravity will cause a siphon effect when the pumps are turned off. If your sump can't hold all of that water, you will need a way to stop the siphon effect at a point where it will not overfill the sump and end up on the floor. A small hole drilled in the pipe at the lowest point you would want your display to drain to, will break the siphon and stop the water from draining back into the sump.
