What's to temp on your mh? If they're in the 10KK range, that might not be helping.

I notice zoas show their best colors with atinic lights. I use to run a 10-14k spectrum then now converted to all blue, i can even see the sparkles on my zoas.

Tell us a little more. How did you acclimate them? water parameters? did they all turn the same brown color?
