My change to a Phoenix DE HQI hallide looks like it has solved my algae problem. It is much bluer thatn the original light. The original light was to far into the yellow spectrum. Now that I think the algae is solved I will remove the UV light.
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)?
