I need help plumbing my 180. I have two 1.5 overflows going out the back bottom. Do I just run these straight down into one end of my sump, or run one to my skimmer half and one to my fuge? Do they connect down there? What about the return? Do I just run a line straight up and then tee it off into a few directions? I am not drilling any holes in my tank, that scares the crap out of me, so no closed loop. I'm so lost, everyone has a completely different setup from the last guy!
