well believe it or not it works! I plan on making a few changes tomorrow though. I currently have a mag 9 as a return pump and a mag 7 hooked to my closed loop. I am going to swap these two pumps around making my mag 9 the closed loop for circulation and put the mag 7 on the sump return. This should allow me to direct all water from the tank overflow through the skimmer and allow the skimmer to empty into my filter sock. I will try and flow around 350-400gph through the skimmer which should be enough flow and plenty through my sump as well. Hopefully this will let all the oily skum water from the tank to enter directly to the skimmer making it a bit more efficient.
