I have been on a 10 year sabbatical break from reefing due to house space and work Commitments. This year we decided to build a new home and my wife asked me if I wanted to design a spot for a tank on the main floor. What we are planning is space on the main floor for a 125 Gallon Display Tank, the sump and everything else will be down stairs in the furnace room. We expanded the size of the furnace room to accommodate a place for a fish room for me.
After Reading and researching on the forum and youtube I have come up with the following basic build.

1. Drill the main tank for a Herbie Overflow System.
Return will be 1 inch
Two Drains for the Herbie will be 1.5 Inch each.

2. I am going to have to deal with 14-16 feet of head pressure and about a 25 foot horizontal run for the plumbing, so the plan is to use a Reeflow, or Iwaki Pump for the return.

I have read thru some of the tank journals and seen some of you have already completed this type of Build. Would any of you reefers that have this type of two floor system please give me any pointers on any problems you think I might be creating for myself. I would rather build if right the first time. We started framing the new house today so I will need the ruff in pluming confirmed within the next month. Thanks for your help.
