Acropora Turaki is a highly sensitive species. Chances are if it began to STN that soon in your tank it may not survive. I lost my mini colony not even 48 hours after introuducing it to my tank. Even after fragging it up into smaller colonies, the necrosis started right back up. Dale warns that if it is exposed to air for evevn brief amounts of time you can kiss it goodbye. So if you are going to cut it do so under water, same goes for gluing it. As far as dipping it, I wouldn't as it is already stressed from the change in environment. Just cut into the healthy tissue and glue it firmly to an area of low flow in your tank. Sorry to hear this Don. I feel your pain and good luck.
