I think that statement is both true and false. I think if the color is coming from zooxanthellae flourescing then the white washes it out. If the color is just coming from a pigmented solid color then the white will bring it out. That is why the carnation frag I have responds inversely to the test to make my rics and blastomussa look better IMO. Also why a lot of fish don't look as good under very blue light.
I had an led that I was using before the photon 16, that had mostly 10k whites, a little bit of 65k for the whites. Now that I have switched to photon 16 the colors are about 25% better. I also have a blasto with bright red on it and that looks better as well. Sometimes I wonder if certain corals even if they are the same color as others, that the xooanthallel just reacts different under lighting.

I created my own layout, got rid of the reds and greens and added uv's in place and rearranged the layout. The light looks good but alittle pinkish, I too have turned up the whites and lowered the blue to get a better visual affect. I am going to sell and go back to MH with LEDs as accents as my SPS did not like them.

I have 4 20000k leds in each D120. They look almost the same as 12-14k. But 20000k will have a stronger blue spectrum a little more green and a lot less in the red and yellow.
IMO it is the green 520nm LED that washes out the tank. 500nm is much better.
Also add some yellow and red. My tank no longer looks washed out. It now looks as good or better then metal halides. Where as the stock Evergrow full spectrum looked really bad to me.
I have a lot of UV in mine and it is not pink. But I have a wide variety of LEDs.
I would get wide range of leds from Logan and experiment. LEDs are only a couple of bucks each.

Is this true.
"""""dimmers do not just reduce the intensity of the illustrated spectral curve, they cause a spectral shift, which stresses your coral.* Dimmers and "controllers" most definitely do not help acclimate your coral, or help your coral at all - in fact, they do the exact opposite, as do 'storm modes' and associated "features".* This is why you will never see these sorts of "features" over very high end aquariums, or in aquaculture facilities or public aquariums, and why would you?* They're completely unnecessary, and can be harmful.* """"

I'm curious how long you tried the LEDs before deciding to switch back?

Nope. According to a calibrated spectroradiometer, the spectrum shited maybe 2nm. That is in no way harmful to corals, and makes no difference. Storm modes do not effect corals, but they do scare fish.

I've had the fixture for a couple months now, it has nothing to do with the fixture and everything to do with me. I don't have time to figure out where everything needs to be set.
Its not like T5's or MH's, you could figure out how many watts per gallon you needed, the colors of the bulbs were already set for you, you knew how high to hang them above the water surface, etc...my corals lost color no matter what I did, they cost more than the light so they won. When more is known I will attempt again.
As I said before, very well made.
So to hear your corals aren't doing good.

ok so here is a question logan.. if like like the photon32 set blue channel at 10% and the white channel at 100%. any suggestions on ratio on the next order. seems to show more of a contrast on the rock and my regal angels look so much better.. yellow is a more true yellow..
thanks

I would try more 480nm, and swapping half of the 4500ks for 14k cw. 480s hit a protein (perodinin) know for giving off a brick red color.
