I wanted to show the difference in one of my tanks after about 8 months with LEDs.
Before Leds:
About 8 months after installing LEDs:
There was a little rearranging, but not much. Over all the colors are so different. In the bottom left of the bottom picture, see the neon green yuma rock? It is there in the top picture too, just not neon.
Two days ago i installed some UV-B Led strips to see how it would affect the reds. The only changes so far is the blues. Tips of acros and monti rims are turning to a bright glowing aqua blue. At night after my lights go out anything neon green ( hammers, kryptonite candy canes, etc...) keep glowing. Yes, glow in the dark. Not super bright, but you can still see them flouresence.
Here is what my monti looks like now after about 10 months:
I have no doubt LEDS can grow coral. And make them beautiful. As stated before all my softies that were red and changed to orange, are still orange. Hoping the UV will help, we will see. Hard corals that were red seem to have no change, they are still red.
