I want to thank you for pointing this out to us. I have not had a lot of time to absorb all the material, but feel very much vindicated when reading Myth #5 "The "K" rating of aquarium lamps plays an important role in the coloration of corals"
The author reinforces what I have said for a long time , it is total irradiance (Lux), not color that is important.
I just hope that those who believe differently will read this article carefully.
