Refugium

I am setting up a 125gallon and was going to use a sump under the tank. I really dont want to do this since I am scared of it overflowing. I would much rather do a HOB filter/skimmer. Can a refugium also hang on the back? The tank is 72"L x 18" W x 24" H.
What is the basic equipment for a fuge?
How does the fuge water pass thru the tank water?
Thanks
