So you like the Phoenix bulb? I've been wondering what bulb to use on my tank... do you find it very blue in general, or just compared to the other bulb (which could well have been a lower quality 10K or even a 6.5K bulb)?

It is very blue. The original CadLights was a 14,500K as well. In addition I have 2 very blue Geisman actinics that really exagerate the blueness. But if it is helping me deal with the algae then I will put up with it for a few more months.
