I got it out of one of Fenner's books. "The Conscientious Marine Aquarist"
" Many marine aquarists have found they like the effect of adding 03
actinic, or blue actinic, flourescent lighting to their systems. These bulbs tend to bring out the flourescent greens and blues of fishes and corals, and they do work well as gentle lighting during the dawn and dusk periods in systems that have timers (and the number of different, separately wired bulbs) to accomplish this. Keep in mind, however that full spectrum lights still provide the most biologically effective lighting power, and the actininc may be doing more for your eyes than your specimes. A generally accepted recommendation is one blue actinic blub in combination with three full-sepctrum flourescents."
-Robert M. Fenner, "The Conscientious Marine Aquarist"
whoo that was a long one LoL, hope it helps to clarify. I typically trust what Fenner says as most people highly respect and believe in his work. I have used this method in my tank and really like the results. i have 6X65W full daylights, and 2X65W 03
's. I keep the actinics in a central position across the tank to shine on the LR
and then blast the rest with full daylight.
Here's to swimmin with bowlegged women.
