My email to him
I got some information now from Fluval and posted it on the site. I have more to go over, but those zoas would probably like being placed a little higher. Also, have you heard of stripping your water, or water is too clean? I think you may not have enough nutrients in the water for the corals you have listed. From the pics you sent, the tank appears almost too clean. I am afraid your elegance and bubble tip are probably toast, start feeding your tank a little more each time slowly so that the fish can eat it up without leaving much on the sandbed. I will hopefully get a chance to look at more later
