"Crisp, white, blue" hmm.... Mine seem abit yellow tinged still. How blue are yours? Can you post pic? I have pics of my tank but not downloaded yet. When I look through the ends of the tank, I notice a much more distinct yellowing. I run carbon 24/7 btw. I'll try to post on my day off. So far I'm not impressed. I'm at 3 and 9 o'clock with my orientation.
