I don't mean to answer for the doc, but 36" deep would have some problems. First and foremost, lighting the bottom would probably require 400W halides (or probably T5's with great reflectors) if you want SPS or clams anywhere near the substrate. If you're short like me, you'd have a tough time servicing the bottom of the tank as well. But your dimensions sound incredibly beautiful and I'd love to see it! BTW, good luck with your residency ... shouldn't you be in the OR?
