yet another LED lighting question.....

[nitrogenbubbles]

Yes, another.....I searched the forums for my specific problem and found nothing in the threads, sorry in advance.

So my latest build is heavy in 410/460nm (3:1) with full spectrum ((approx 10%) and cool white( 5% <claims to be 10KK, but I don't believe it...looks nothing like a XM 10KK MH>) anyways, ran into a first?!?! Subject coral, yellow coral I personally saw in a tank with radions . Get home and it was radioactive Green, and I mean blinding green. So, light 101....blue and yellow make green, right. What color must be supplemented to bring back the yellow? I have tried red and more white without avail. Sad, because this favia was a beautiful yellow.

Cheers

Someones answer.. Don't think I can post where it was from due to site censors..

I have a fascination favia piece that once displayed multiple colors... Green, yellow, red, etc. See the pic attached... this is what it looks like when I received it.
After 4-5 months, it's growing great but has changed color to almost one color... green. I noticed on one side of the piece (maybe more shaded area) a tiny area that is it's original multi colors (yellow, red), but that's the only spot.

Yes try Lower light. Fluorescence is or should be. inverse to growth. So higher light more glow. Green in your case.
Keep an eye out for browning. Nutrient build up.

I definitely suggest moving it down in the tank. Below is a picture of mine under Kessil A360WEs before I added T5s to the Kessils. The Kessils are about 8 inches from the surface and the favia is about 16 inches below the surface. You can tell the light is to the left of the coral because there is more green on that side.

Thread ended w/ out saying if it worked or not..
