You are totaly confusing improper care of the corals / reactions to stress with the "elegance coral disease". In short, you have figured out how to properly care for an "LPS", and thats nice. But have nothing you can say is research or a reason for the disease. In fact, I would not even use the word theory, besides it being way off the mark and incorrect, one has to be able to provide reasonable facts to lead one into a theory. Just guessing that a coral has "skin" or a thicker one at that, is meaningless.
Again, its nice that you have taken good care of some corals, its a shame you had to figure it out the hard way though when such information is readily available. And with that, I'll leave it at that.
