Both your pics look great. Love them both, tough choice lol.
Yeah, it's preference... There's one coral frag I have that I thought was purple. Then under the 14,000K lights, I realized it was green with purple tips. Oddly enough, the 14,000K seemed to bring out the other colors in that particular frag. But as long as everything still grows under the 14,000K as well as it did under the 10,000K, then I'll stick with the 14,000K for a while. Maybe another 20 years....
