I haven't seen any of those little stars in my tank but I know I've seen them plenty of times before in other tanks, or in liverock tanks at aquarium stores. I can say that the corals seem to be doing better, a couple of them definitly are and the others have at least stopped dying and are stable. It seemed that once I raised the alkalinity things got better. I could probably also use a little more water movement in some areas of the tank. I appreciate everybodys help.
