BRILLIANT!
Are those 2 Reefbreeder Photons?
Your horizontal runs of pipe are going to restrict your drain flow a lot, might be something you have to change in the future. Easier now before it's wet.
Yes they are good eye. A 48 in front and a 32 in back. The head loss calculator gives me about 650 gph which is low for tank turnover, but about all I want running through my sump (between 16 and 18x sump volume, don't really want more than 20x.) Not too energy efficient though, it takes a mag 18 to get that. I'll eventually go to a dc pump if I can find one that will overcome my head pressure and still put out 600-800 gph. I probably should have used spa-flex on the return to eliminate those 90s and 45s, but I'm a pipefitter and couldn't bring myself to do it.
