I also had some issues with my red corals when I switched over from T5 bulbs to the Vertex Illumina.
The red montipora corals turned a drab brick color for quite some time.
I added two mulicolor modules and, later, two more royal blue modules and the corals have regained their red coloration.
I am not sure if the new LEDs had anything to do with it or not. I just think it took the corals a longer time to adjust to the new lighting than other colors.
The green corals all responded very quickly to the LEDs.
Here's my current graph.
3ft SR260 hung 9 inches above a 120gal (48"Lx24"Dx24"H).
6x Standard Modules, 2 Multicolor Modules and 2 Royal Blue Modules.
I have noticed that my LPS (specifically lobophyllia sp.) do not like it when I increase the red or green LEDs.
How are other people's experiences with LPS and these two colored LEDs?
And here's a couple of top down pics showing the colors I have now.
The rock in this last pic tipped and busted out quite a bit of coral, but you can see that the Vertex Illumina LED fixtures do grow colorful corals.
