Ruth, your skimmer will qualify as massive. Especially because it is so FAT!
Here is a page with the dimensions

And those MSRP prices WOW.
What corals do you plan on keeping in this tank (this will determine the CL pump) The mag 7 would be a good return pump IMO. Is your skimmer custom or can you look up a manufacturer suggested feed rate?
