Looking for comments/suggestions on my new tank pls!

[LostMind]

Ok, I have mentioned a few times I have ordered a larger tank for my basement rec room.

It's going to be an inwall tank, with its own room for equipment and such (noise bugs me, so I want the equip tucked away from the viewing area... currently the tank is in my living room and way too loud). Unfortunately, I can't get proper plumbing to the equipment room tho. So I have to hack some stuff up a bit...

Tank size is 7' long, 3' deep, 2' tall.
Two overflows - one in each corner. Each should be capable of 1000gph each.
(eurobracing, black silicone, ground n polished blah blah if anyone cares)

Current plans for lighting are to run four 14k, 400w SA bulbs in reflectors. I think I wont need actinic supplementation with this setup - any comments? Should I look into other lighting setups?

For flow, I am planning on the following:

Return pump - ampmaster 2100
Closed loop - ampmaster 3000
Powerheads - 2 x Tunze Turbelle 6110

I figure that should give me roughly 30X turnover. I think that should be adequate for my sps dominated tank. I am finding it tough to get more flow without cramming the tank full of powerheads (the tunze's are amazing tho, I have one running in my 120 now.. wow!)

For my skimmer I am a bit uncertain. I have been talking to the guys at Mazzei corp, they recommended a few injectors to play with. I plan on placing an order with a company in chilliwack next week and getting a few injectors. Am leaning towards building a skimmer powered by a mak4 feeding two 1078 mazzei injectors.

Otherwise, I am thinking to just purchase a big ass bullet type skimmer from JL and just drop a thousand bucks or so (ouch).

I am contemplating building a calcium reactor based on DJ88's square design he posted a while back.

For the sump, I have a few ideas. I currently have an oceanic model3 sump that is modified to hold a bit more water then it was originally designed to. I COULD use this as my sump, but I feel it is a bit small for the purpose. I do have the 120, which I could always drill, but then I'd have to get glass and add baffles and such. I could purchase a bunch of acrylic and build my own sump, but I have very little experience in working with acrylic and I am not sure I am up to building a decent sized sump on my first run. Anyone got any ideas for me?

I am planning on migrating my RO/DI unit to the equipment room. Even tho the room has no plumbing, I am thinking to put a splitter on my hose and run it into the equipment room thru the window. I'll just have to run the return/waste line out to my drainpipe thru the window. With a couple floatswitches in my buckets I should be okay. If I have a disaster... Guess I will move it all back into the laundry room and lug those buckets around...

I plan on only having 1-2" of sand in the tank. Approx 200-225lbs of LR in the tank. Probably another 75-100lbs in the sump. I am hoping to have a lot of empty space as I want a fair amount of fish in the system... so I want some decent swimming room. A couple tangs or maybe a small school of anthias? Not decided yet. As for corals, my 120 is pretty packed with frags right now (thanks mostly to Wendell and Jack) and I am thinking to just migrate those to the new tank and leave things as is so they can grow out nicely... unless I see some real beauties..

I am pretty tired right now, so I probably missed something along the way. Any feedback would be welcomed! Especially if I am missing something glaringly obvious... hhmmm, like a top off setup. doh!
