Ya know, I really can't say whether or not the coral looked better with those lights, cause they still look the same to me without them lol. I believe you are correct on the whole spectrum thing about upping the k. I believe that was what they were saying. It changes it so that the nuisance algae doesn't grow well. I can narrow one spot to the lights in the back left corner, but one spot in particular is right under the center metal halide on a bleached rock from the 75g. But since we have done the lights out, it has improved tremendously. OH, and I do remember nikesb saying that there were reports of cyano outbreaks when using these lights. I think that the brown fuzz meowzer and I are having is/was thriving due to the spectrum from these type of lights.
