Can adding Mg or raising Alk make sps tips turn Flourecent green?

i have noticed this fluorescence especially on the white deepwater acro that i had placed just below lights. b/4 i thought this was acro's response to possible over exposure but now i'm not so sure. anyways i look at this as a bonus hi-lite feature.

I noticed this as well with my deep water acros, ironicly my yellow hi-liter now has those same bright tips as the deepwater acros where the coral is growing. I guess when the coral gets big enough to frag there may be some takers with this unusual coloring tips.

my deep water was originally all green under 400w but now with t5 body is going purple hue and tips are flourecent green. Did you change your bulbs? Maybe when your Ca and alk levels are in check plus you're dosing Mg it may have made your corals colour up different. I can say that my freind fragged me a nice piece it was brown for a year never grew but with my t5 it has put on half an inch and tips are flourecent green aswell only I never dosed any Mg until a week ago silly me...

Tang Daddy,
I have not changed bulbs since May but did add 2 Glo t5's to the display a month ago. I figure it is the addition of Mg that may have caused the change, but the tank is still looking good so I will go with the flourecent green growth tips being of no concern until I see a reason to think differently.
