However its going to depend on how much water drains off after the pumps shuts down. you can always have a small hole drilled into the return line. Just above the water line so the siphon breaks the water there.

The drain in my tank has a little whole at the top with a plastic tube sticking out of it. So I don't think there will be much water draining down as soon as the power goes off. I guess I'll have to check the depth of the drain and the water level I'll keep to calculate the amount of water that might drain down.
