90 Gallon reef set up

[Trigs]

I have been working on plumbing and everything else as i have been going, i have set everything up to this date running a single over flow with 1" bulk head to a T and straight pipe down into the sump with a ball valve control. The fist chamber in the sump is my skimmer and my micron bag, then a fuge, and then baffles and return pump.
