To me it seems like you may be a little low on LED's, and if I remember correctly your LED's with 60deg optics should be spaced about 2" center to center, or raise them higher from the surface.  You may be ok with what you have, but if I were doing it I would use 30-40 LED's on it, and dimm them to get it just right.

24 Led's with 60 degree optics that close to the surface is going to out perform a 250w MH. I have 24 over my redseamax without any optics on them and i'm confident that I can grow anything wherever I want. (and my tank is 26" high)

My suggestion would be to wait it out a few weeks and see what happens, if everything is open and happy, save your money. My guess is (especially if you aren't dimming the led's) that you are just fine.]]> Thu, 28 Jul 2011 21:41:26 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425437&title=lighting-a-60g-cubish-column-tank#425437 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425420&title=lighting-a-60g-cubish-column-tank#425420 Author: laynframe

I had a 250 halide above my cube, 24X30X24, for about 2 months before i switched to leds but i grew sps on the bottom with no problem]]> Thu, 28 Jul 2011 19:15:40 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425420&title=lighting-a-60g-cubish-column-tank#425420 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425418&title=lighting-a-60g-cubish-column-tank#425418 Author: bstuver

Actually no I just moved everything over and it's all open and happy:) I just didn't know if I had enough light. You think I have enough?]]> Thu, 28 Jul 2011 19:09:07 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425418&title=lighting-a-60g-cubish-column-tank#425418 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425415&title=lighting-a-60g-cubish-column-tank#425415 Author: Ahanix

Yes they have 60 degree optics I do believe, I think that is what I ordered lol. I can move the light up or down it is about 6-8 " off the water right now.]]> Thu, 28 Jul 2011 17:51:28 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425411&title=lighting-a-60g-cubish-column-tank#425411 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425409&title=lighting-a-60g-cubish-column-tank#425409 Author: Ahanix

Are you running any optics on the LEDs? How far is it off the water? You could go with 36 LEDs. But I wanted to.see if it was a spread issue more than actually having enough light ]]> Thu, 28 Jul 2011 17:27:51 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425409&title=lighting-a-60g-cubish-column-tank#425409 http://www.utahreefs.com/forum/forum_posts.asp?TID=50427&PID=425404&title=lighting-a-60g-cubish-column-tank#425404 Author: bstuver

So I am using my LED fixture over this 60g tank. And it almost looks like enough light but not quite. It has 24 LED's that are 3 w cree. I was planning to add a halide to it as well but I don't know how well this will blend, so what I am wondering is if I just stuck with all LED how many more would I need?
The tank is 30" deep and 20X24"
