^^^ That is a wealth of information. I'm going to have to check out the website.
That guy comes across in a very non productive way. He is a hobbyist nothing more an art degree, and president of a reef club make him an expert. several people have had success with these corals as well as myself. Are these corals difficult to keep sure, but so are any other coral if needs are not met. Low flow, target feeding, proper light, seem to be the "expert needs". If you are willing to put the research in then this coral can be successfully kept.
