Well its still up in the air about doing leds or metal halide. Id like to do leds but from what iv seen on line there super exspensive. (Although almost all other types are too =\) but I think the extra I spend on it would be worth it for the leds. But some ppl have told me that leds dont give off enough light for corals.

That's not true at all. LED's have come a long way.
Realize that with MH, you will be replacing those bulbs every year, for about $60-100 a piece, creating a lot of heat, which can be a problem, and sucking the power company dry.
I run T5's now, which work great, but will be upgrading to LED as soon as financially able. My T5's cost me $400 annually in bulbs alone!
There are cheaper LED's out there than the Radions and Al Sols, that do a great job growing corals. They are efficient, create virtually no heat, and have an estimated 10 year bulb life. For me, it's a no- brainer!
I would research carefully so you don't end up regretting it later.
Metal Halides and T5's work great, but they have their drawbacks.

Some like the radions and sols are very expensive but the quality and feature make it worth it in my opinion. However for cheaper leds that work very well and have a great following, producing excellent results look into kessils. They just came out with strong and dimmable version of the a150 called the A350. A150 is priced around 250 and 2 of them over a 55 will be perfect totaling about $500 and they last 50,000 hours (~5-10yrs) no bulb replacement, no heat, and about 70% less energy than halides.

Doe leds have the diffrent spectrum range? (I'm guess that's what it is?) As in where the metal halide have the white lights and then the blue moon light bulbs?

Yes, they are different colored LEDs. The more expensive fixtures can be controlled to ramp up and down the blues and whites automatically. They can even simulate lightening storms.

The cheaper ones, like the ones I use are only blue on/off, white on/off, which was plenty good for folks that used halides and/or t5 fixtures. They all glow corals though. I have acropora growing like a weed and very colorful, 24" away from the fixture.

Alright.that's what I was worried about. I have one light fixture on my 30g fowlr which has a white bulb and a blue bulb but there wired together so I know that I needed the two. Idk I got my tank pre-set up and don't even know what kind of light it is or wht the wattage is. I got it on craigslist and haveny been able to get ahold of the guy in like 2 months. All I kniw is its a coralite.

That doesn't matter. We turn on and off whites and blues at different times for our own enjoyment. Corals don't care about that. All they want is enough light for enough time.
turn the fixture over and read what it say on the lamps. It should tell you the wattage and the color.

I thought the blue bulb puts off longer wave lengths that go deeper in the water than the white bulbs.

you can grow corals fine with just daylight lamps. People use the blues for a deep water look, and to color up the corals more to the naked eye. You will see when you go to a store or to someone's house and pick up a few frags, and get them home and when you put them in your tank they look totally different. This is just because of the amount of blue they are using to make them "pop".
If you ever get a chance to see a real reef in person, you will see that it's not crazy blue like people have their tanks, and the corals don't look as bright.

Yeah I really like the blues. And I'm planning on getting scuba certified eventually as well. After I get my aa I'm planning on transfering to a school on the coast for marine biology. =) I think seeing a reef in person would one of the most amazing things ever.
