You gotta remember that he has been reefing for a long time and been slowly moving away from the bio-balls and most of the times he uses real ocean water which i think is awesome.  He was doing crazy stuff at first i just like watching for the variety of tanks he works with.

you can save more money building it yourself i run 48 cree 3w over my 90g 24 white 24 blue i think the formula for figuring out how many led's is LxW divided by 20 for soft coral 10 for sps the guy that built my led's i think runs 96 cree 3w over his 120 shallow but they are not at full power because its a shallow tank only 16in tall i ordered mine from rapidled.com you could prolley call there costumer service and they could help you out with all the details for how many you would need and what not. for a 24in tall tank i run 60 degree optics on mine the best thing to do is too buy the amount of led's rapidled.com says you need them get the dimable drivers and do turn them up or down and measure the amount of light with i think its call a par meter and do what you need for proper light for corals. also i wouldnt suggest buying a diy kit inless you know how to soder or inless you know someone who knows how to. here is some a youtube series on building led's for a aquarium. its 1 through 4.

thanks so much man

no problem any other questions just message me

my new led fixture is going to be 160 leds :/  thats going to be a long day project
i'd do 2/1 (2 blue 1 white  )   i would mix the colours like blue and royal blue, and cool white and warm white

My first LED light I built like that and was very disappointed in the color it produced with the mixed LED's. The tank looked more green than blue. My mix was 12 blue, 28 RB, 10 cool white and 10 warm white. I ended up pulling all but 4 of the blue LED's and replaced all of the warm whites with cools. I do prefer a more blue 20k look to my tank though. 2:1 blue over white is the ratio I prefer also, just not the regular blue Cree's.

yeah i know what your saying, i may just go with the the same leds i have on my nano tank,  it has just cool white and royal blues,  it has a nice purple look.   but im adding 8 more royal blues to the nano on thursday, so i will see how i like it then!

im not sure about me using the warm whites on the frag tank yet though, because the colour is not so white.
