120 SC Aquarium setup help.

[amazonjoe]

Just received my 120 gallon. I also got the 57 gallon sump and 302 skimmer.

The skimmer only fits it that area. Help with setting up pls also trying to figure out the plumbing. It has 3 holes. 1 is for return, the center one.

Little off topic but what is the measurements for the skimmer section? I'm building a sump and my 302 is already in a different sump that was built for a different skimmer.
