Assuming your talking about using cree xpg's or xre's

1 LED to every 10-20" squared of surface area was recommended to me as a good starting point.

I'd say most tend to do a ratio of 1:3 (white/blue) and after seeing how bright the 12 cool white xpg's are I may do the same but I'll be starting with a 1:1 ratio next month probally and go from there.

so would this http://www.rapidled.com/servlet/the-...ourself/Detail be a good start

I would start w/12 just to get an idea of what you want for sure b4 you added more.

If your not worried about dimming the LED's then use this one instead

If you want the option to dimm, then this one

The original one you had wasn't the xpg's which are supposed to be 30% brighter then the xre's

EDIT: also if you haven't done so I would go over to "DIY LEDs - The write-up" and read through some of the stuff.

In the article I reffered to you, TheFishMan65 was kind enough to write up a summary.

depending on the species of coral in the tank you will need at least 40 if not more leds. 12 will get you nowhere. i have a bc 14 that has 12 and a friend has a bc29 with 24, anything less will not sustain all forms of coral and will limit your choices
