125 gallon tank, 6' oceanic, with 20" glass center brace.
This is the setup.
Buy the rest of my lighting of T5 for $371 shipped. 10x39 T5 bulbs, Blue+, aquablue, etc..
Or for $299.99 shipped i can buy 2 250watt MH with 15k bulbs and have 4x39 watt T5 to compliment (already own the T5 backup).

I like this, But I would go 2x250w MH 10k and 4x39 watt T5 420-460nm the T5 bulbs are better at the blue range and the MH are nice at 6400-10000

2 metal halides aren't going to light a six foot tank very well. MH's are only good for about 2ft of tank length. I prefer the MH's over the T5's but that is only a personal preference an individually reflected T5 setup can light a tank as well MH's can.
There is no way that I would run a 6400k or 10k bulb on a DT tank though they are way to yellow for my liking I prefer the look of 14k bulbs and recently I just upgraded to 20k radium bulbs and I really like the look of the radiums they aren't extremely blue just slightly bluer than my hamiliton 14k bulbs.
