"Just what I have been waiting for. Now that we can figure out PAR values for a single pendant at various depths, could someone elaborate or direct us on ideal PAR values for optimal growth of hard/soft corals -- generally speaking? Like, at what point do PAR values begin to scorch and at what level are they not enough -- for hard vs. soft corals. This would help me to determine percentage of blue/white to maintain in my 39G CAD Pro using the AI pendant. "

Talked to a tech at one of the most respected US coral farms on just this issue. He asked not to be quoted in print

. The gist of what he said was, "hit or miss". For example, you might even find strains within species that adapted to relatively higher or lower light levels than you might have expected. Of course, he argues that farm raised corals will tolerate wider variables than wild-caught.
