Thanks! I was worried that I had bought something cheap. I guess I really didn't know what I was doing (again!), and am finding out along the way!

"Dead band" huh? That's what that range of pressure is between the two different spots where it switches state?

And it could be a 12" drop. I only did a quick measure once I figured out it was about 1/2 the height of my 75g.
