I would slowly drip in some water over an hour or more. Also, Bob Fenner in the Concientious Marine Aquariust(sp) claims that starfish do much better if they have some of their original water with them in the new tank. Almost like it is soothed by the scent/biology or something. Suppose to make their acclimation better. I did it with my organge knobby, probably about a 1/2 cup of old water and he's done just great. Good Luck!
