Led question

bkoo29 · 01/10/2012, 08:43 PM

Thinking about starting a frag tank but it is too expensive. So, I decided to turn my spacious sump into a refugium / frag tank. The space is 14inL x 9inW x 10inH. The very top of the sump is 18 in where the light will be hanging from. I want to achieve a 20K color which also can grow macroaglae/plants. So, I thought I would do something like 1 royal blue, 1 blue, 1 white, 1 uv, 1 green, and 1 red. I have no prior experience with led lighting, so I am relying on you experts out there. LMK if this is a good setup to pleased a frag tank and refugium. All inputs are welcome.

throw out the reds and greens, those colors are covered in the natural and cool white leds. keep it simple and either go 2:1 royal blue : cool white, or mix it up a little and go 1:1:1:1 roya blue:blue:cool white:natural white. with the space you have to work with i would go the first setup so you can get better coverage with each led. think about the sq.inches of space you have, then think about trying to get all those leds to cover and equal amount of space over the area. also look into optics to help get focus those leds , it will make a huge difference.
