Is this setup OK?

I'm getting ready to set up a 58 gallon reef(36x18x21). The tank will hold mostly sps corals. Is this sump/refugium a good design? Do the returns look good? The tank will have 2 drains one is a 1" and the other is a 3/4". The sump will have 2 return pumps pushing about 1057 gph each(ViaAqua 3600) going through a SCWD per pump. Lights will be 2x175 MH with PC's. Skimmer will be a ES5-3. Is this the ideal setup? Should I do anything different? (sump, pumps, lights). This will be my first attempt at a decent size tank. Any advise will be appreciated.


Thanks,
