LED Lighting for 90g

I've been saving up money to buy myself new lights. Looking at LED units, currently have MH & t5's and I hate them.

I really, really would love to have some coral! My problem is I know very little about what light (spectrums, colors, & such.. It all confuses me) they need to support them.

Wanna make sure I get everything right before-hand.

I've been looking on eBay but there's just so many & I don't want to buy the wrong thing. I plan on starting with "easy/beginner stuff" but would love to be able to sustain harder to maintain corals down the road.

Also confused on how many units I'd need... Tank dimensions: 25" H, 48" L, 18" W.

Thanks so much in advance for any input.

I've set aside $450, but I have some money coming back from taxes if I need more.

I've seen LED units from $150 & up, so I tried to overcompensate.

Ya 150 isn't gonna grow coral very well in a 90.

My buddy has one of these over his 75 sps dominated reef and he likes it. I run one of the smaller ones over my 20l and it's a little overkill honestly but I like it

What's the difference between 60, 90, & 120 optics, for only a few pennies?

The coverage, 60's cover less area with more intensity 120's cover more area but it's less intense

You don't need optics unless the unit is pretty far above your tank or the tank is deeper than 24". 120 is good enough for most applications.

I have 2 of these http://bit.ly/1eB5SUB over my 90. They will grow any coral you want.

Each unit covers a 24"x24" area.

My tank is 25" deep (not counting sand) and 4 ft long. So two of these ridiculously cheap LED's will light my whole tank? This seems too good to be true!

Also what's the significance of colors offered?

This one is blue/white but I've seen some that are blue/white/purple/etc. What difference does it make?

BuildMyLED.com has great, low profile LEDs that you can use. They are dimmable and compatible with Apex units, too. I use them on my tank and love them. You could easily get them within your budget.
