Yes I found those after I had the problems.
Theres a big one on RC and Reefsanctuary.com as well. I will eventually try it again (slower this time) but I'm just waiting for my tank to return to normal before I try it again. My first indication that something was going wrong was the incredible and almost immediate loss of color in almost every SPS I had. Suddenly everything was brown and I was like WTH is going on? It only took a couple of days for that to happen and then the tissue recession started. Things are just starting to color up again, but they're darned slow to come back.
