Looking to hear some advice for lighting coral growout tank

[caseyjones]

I'm going to be setting up a 200 gallon coral growout system and I'm not sure which way to go with the lighting. The tank itself will be 130 gallons and measures 6' long, 2.5' wide and 14" deep. I'm not 100% sold in T5's yet although that is an option. I want to run halides. I'm thinking 3 250w HQI, Phoenix bulbs most likely with a Lumenarc reflector. Do you think 250 watts is too much? The tank is 14" tall but he water level will probably be 12" tall...so what do you guys think 250w or 175w?
Thanks in advance.

Also I will be building the calcium reactor for this too...how much media capacity do you think I should plan for? I'd like to go with a cylinder shape but for ease of contruction and cost I think I am going to keep it rectangular. I was thinking 6"x6"x18"tall.
