I'm glad you asked... I had hoped this contest we would all share our methods...
I'm been actually experimenting with LEDs... I bought a set from "Waves of Glass" from SDreefs.... where I could specifiy the color freq of all the LEDs.. I was a relative newbie to SW... and so my first purchase I bought 120 W fixture with 3 separate circuits. One with 63 16000K W LEDs and then one with 28 453nm blue LEDs and ONE with 28 440nm LEDs. I did this because I read that most corals sweet spot was closer to 420nm, but Larry M told me the look LEDs in that range was very purple to the human eye, and afterall the purpose of my aquarium is to please my eye.... so on a couple recommendations that is what I tried...
I also have a standard 10000K and "royal blue" LED fixture over my frag tank... which I picked up used. It not the same powerful PAR reading as my main ones but works well for my 18x18 frag tank...
Well I've yet to get any appreciably PE on the SSC... but his last week I've seen some hint of PE... which will bring me to my main point... A couple weeks ago I decide to go and experiment with the lighting... as I had noticed that I would take frags from my frag tank with great PE and then add them to my DT and PE would go away.. What would cause that..?? Water was same... Frag tank is plumbed into my sump... Currents?? I experimented with that... I lower my lights, I raised my lights.. and found I beleive these MAIN LEDs are really really putting out a lot of light, to the point the corals didn't need to extend to get what they needed... but I also was wondering whether the light sprectrum had anything to do with it... as my simple LED fixture over my frag tank was allowing nice PE...
So I went out and bought a new LED fixture with 63 12000K Whites and 28 453 B and 28 468 blues.... to see what affect this would have. So I have one of the older ones and the new one over my DT, First I noticed this gives me a slightly better look to my eye... The whites are NOT as STARK.... There is a little more yellow to it... only noticed when compared to the 16000K.. But the real thing I'm noticing, is I'm getting a lot more PE... Which I'm equating to a good thing.... I've only had the new light for a week, so I'll report more by the end of this contest.... Hopefully one side of the other will show some difference.
