Will this work? It sucks from the bottom and the red line represents the water level in the event of a power failure...... Or at least that's the way i see it.

Here is a slight variation of your design that I made for richardhmc. He has the overflow in the wrong tank, but you can get the idea how it works. I have used this design on fry tanks. It has a lower flow rate than the DIY overflow in the sticky thread because the tee is at the waters surface.

I flow tested the one I made for richardhmc and found that it was piss poor. I had to make him a second one; his tank is a 55g. I don't remember the actual flow rate though. You will have to play with it and find out. Expect to use large diameter pipe through out. I used 3/4 inch for the inverted U pipe.
With two overflows made with at least one inch pipe, you should be able to get in the range of 300-600 gallons per hour. The farther below the surface your tee is, the more flow you will get.

Go back to that picture and look where the tee is. It is vented, so the syphon will be broken when the water level reaches the tee.
