Looks good, are you using the 3/4" c-channel? Thanks for the details, this will be perfect in my 90G canopy.

yes all i am using is 3/4" C channel and it is working great..just make sure u have some fans. I have 2-4" fans blowing from each end of my 72" canopy and my heatsink stays very cool. The fans do make a big diff! when i first tested it, i thought i didnt need fans at all. But after more testing it is alot better if you have at least 2 fans blowing towards each other on each end of the heatisnk (c channel)

I think it was actually 96" if I remember correctly and I know each strip was right around $10

Ok I found some 3/4 U-channel from Ace Hardware and it was 1/16 thickness, I also went by a metal shop and they told me 3.00 ft but that was for 1" 1/8 thickness is there any advantages in the wider and thick material.

The wider thicker material will have better heat dissipation. Meaning it will run cooler with the same amount of LEDs on it.

YEP thats true..the more surface area you have the better job it will do at cooling. I did the 3/4" because it was cheaper and available.

Hey bud,
I love the build, and the tank. I am getting ready to order my kit and had a few questions, I hope you don't mind me posting in your thread. I have a 90 gallon 48"x18"x24" and am going to order the 72 led kit with mean well drivers. My question is should I go with a 2:1 ratio of blues:whites, with 50% 10000k and 50% 6500k, or 1:1 ratio of blues:whites and do the 50% 10000k and 50% 6500k. I am going to order an extra driver to control each color separately? I am looking for a 14,000k look, I don't like too blue of a look but I want a semi blue look, confused yet? Last question is if my lights are around 10" from the surface should I go with 80 degree optics.. Thanks a ton,

Yes 72 LED will be plenty for your tank. Just build a c channel heatsink and spread the leds out evenly across the tank and u will get *****en spread. If ur looking for a 14k look then you will def WANT to go with a 2:1 ratio. I have seen a 3:1 ratio and it looks too blue. I have also seen the 1:1 and it looks 10k. The whites over power the blue and it DOES NOT look good IMO. If it were me i would order:
48-Royal Blue 8-6500k white 6-10000k 4- 420nm violet 3-4500k 3-Cyan that would give u a pretty sweet full spectrum fixture and i would def do 80 degree optics. the 60 would prolly be too narrow, my 80s look great. dont run optics on the cyan, 4500k, or the 420nm good luck |

Thanks for getting back to me, I will probably go with the 2:1 RB to W, I dont know if I will go with the exotic colors right now. I am picking up 10 BL 4500K from a fellow reefer this weekend. So if they look too blue to me I will have some NW to balance it out.
I am also going to pickup an extra driver so that I can tweak the colors a little more, I will run each color on a driver. If I go with the 2:1 with no exotics would you recommend the 50% 10k and 50% 6500k, the 50% 6500k and 50% 4500k, or 50% 10k and 50% 4500k.. Thanks for the help, next I have to begin designing the heatsink. What do you recommend for distance between the LEDs from center to center, and the distance between the rails. Thanks Again,

Change of plans, I am looking into the full spectrum that you stated.. LOL I am going o see if I can work it out. I am glad I will have the extra 4500k in case it looks too blue..
When I build the fixture, do you make it the size of the tank or a little smaller. my tank is 48x18. Should the fixture be 46x16.. Thanks

I built my channel 62" long so I had 5" on each side. Distance between LEDs were about 1" or little less. And I spread out each channel 3" apart. As far as the color mix, I would do more 6500 and fewer 10000 and 4500. The 4500 is really yellow, but I have heard of some Guys liking that look, but I can't say because I haven't seen a fixture with lots of 4500. I'm only running 5 on my setup.

Thanks for the response,
I am going to start building the fixture this weekend, I have taken your advice and going to run the violet, and cyan. I only got the 4500 because a fellow reefer had them and there were a good price. I may order the kit with 50% 10k and 50% 6500K, and since I will have 10 of the 4500K I should be able to tweak the lights to my liking. I will keep the 48 RB and have 10 of each white. That way with the RB, white, violet and cyan I should be able to tweak the lights for a good spectrum. Thanks for all the help, do you have any more pics of your tank, and did you switch any LEDs out like you talked about.

Hey guys, I am considering getting these lights to hang over my wife's 20L. I like the 14-20k look with lots of pop. Can u guys recommend a good ratio? I was going to get the 24 led kit. Should I use any magenta led's or just go blue/white? Oh yeah-no planned SPS for this tank, so only LPs and softies. Thanks

Thanks Schnitzel! Last question- would the 16 inch heatsink be ok on her 30 " long tank? I really dont like the look of the c-channel stuff, she doesnt have a canopy.......what degree optics/height would you use for full coverage with a fixture that is 12" shorter than the length of the tank....? Thanks
