Basically, I bought a float switch like this http://www.amazon.com/Aquarium-Water-Control-Plastic-Switch/dp/B005FDT02Q/ref=sr_1_6?ie=UTF8&qid=1406740109&sr=8-6&keywords=float+switch and clipped it to the rim of my tank so that it activates when the water gets higher than it should under normal operation.
There are a lot of different ways to wire it up so it shuts off your pump. Perhaps the simplest would be to connect the float switch to a relay that controls pump power. In my case, I have a custom built reef controller that I made using a Raspberry Pi. It does a whole bunch of stuff, including monitoring levels, temps, Ph and texting me when issues arise. It was relatively easy to wire the switch to the Pi and modify my program to shut off the pumps if overflow was detected. It also says "Main tank overflow detected, shutting down pumps" in a cool robot voice ;)
I'm interested in the same thing. I've only gone as far as to install one of these to get alerts on water level:

I have a sump though so it's probably much easier to put one down there than on the top tank.
