Hey ya sorry I should have specified, its a 48" tank, but I dont think there is a need for a 48" heatsink, Im just really looking for concentrated light focused in the middle, where I can keep my sps and anenomes, and keep my other less light sensitive corals to the sides.
And also ya my first post I was looking at different set of lights instead of these Cree leds, and I know having 240 watts of LED is overkill so I was just going to stick with these 24 X 3 watt so aprox. 75 watts of LED power. I think it should be good enough. For the total cost for the DIY im looking at $300 shipped.
