[StirCrazy]

Hey Darren, like I said no problem, I just wanted to throw the idea out there :D .

Troy, I totally agree, IMO the main cause of "shimmer" is surface agitation. If I ripple up the surface of my fresh water tank I can get it, very faintly but I can get it :D

Victor, I agree with you about there adapting but, I think the idea of the article is what we need to do to get the specific colors. For example to get a UV fluorescing pocilloporin to fluoresces a violet/blue light (400 to 470 nm), we need to provide it with light from 310 to 380 nm (UV-B and UV-A).

I used this pocillopori as an example for a reason, no where have I read or heard how much UV we should have or how much, is too much.
