50g SPS reef build

[salty child 79]

I currently have a 150g tank that has been running for about 1.5 yrs, and is doing good. But it is time to downsize since I have started into a few other hobbies and will be moving out in about a year.

So here is the plan equipment wise:

TANK/stand-
50g rimless/braceless aquarium
-Holes will be cut in the back left corner for overflow/return pipes.
Stand will be the one shown in the picture at the end of this post.

Return Pump- Eheim 1262

Powerheads/closed loop- I am still up in the air about this...help me decide

Substrate-NONE

Sump- 20g long with 10 inches of refugium

Skimmer- Still up for debate...you choose
1. EuroReef RS 80
2. EuroReef RS 100
3. H&S 110-f2000
4. Tunze DOC 9010

Lighting- Another topic of debate, but i have narrowed my choices down. The lights must be able to hang from a pendant and yes heat is a problem, I am in Florida and DO NOT want to run a chiller, so t-5 is probably the best bet. Here are my choices:
( i would like a 20k look so these would be run with mostly blue bulbs)

1. Aquactinics TX5 5x39w
2. SLS Tek 6x39w
3. ATI Powermodule 4-bulb
4. ATI Sunpower 4-bulb
5. ATI Sunpower 6-bulb

I think that that is it. Criticism welcome and tell me if you would do it differently!!!!!!!!
