Wow,
What a tough choice, under 10k, looks very bright in all areas of the tank, very little shading going on under that lamp. That said, I think it looks awesome, too many out there hiding imperfections under blue, lol... Your corals only look better, if that is at all possible
I would be afraid to see my tank around the 10k mark, I need the blue, lol... One day I suppose, ha, ha... Tank almost has that bright zeovit look under 10k, which is what is preferred based on their original guidelines, I could be mistaken though, haven't read zeovit manual in some time, lol... Based on the pics I viewed, I think the depth perception and coral distinction is heightened under the 10k lamps. I really like it, though I am prone towards zeovit looking tanks.
Best,
