water flow

[wrasseking]

I have a 9 gallon nano wave made by aqua medic. That was basically set up as far as protein skimmer,water pump, and everthing to do with its small refugium filtration. Any ways salt water bug bit me, 8 months after setting the small 9 gal up I'm setting up a 120 reef tank. and I am at the stage of building a refugium. I am putting the water pump in the last chamber what i'm asking is how much gph should that pump be putting out. and by the way the refugium tank is a 30 gal. also i'm planning on putting 125 esu super skimmer. does anyone out thier have any input on that particular skimmer.good or bad or neutral.

For a 120, I would move 900 to 1200gph through the sump.
