Thanks guys for the comments. The sun coral usually starts to open an hour or so before the actinics go off. This is generally when I start feeding. I feed any of the heads that are open, then stop and wait awhile until more heads open and repeat. I have been feeding it at least twice a week, probably 3 times a week. My duncans are starting to extend again, now that the bicolor blenny is gone. So I am happy about that, I was just hoping that it wasn't too late. As far as the algae, it came down to a lot of elbow grease. The snails help, but just keeping at it was what did it. I still have it and probably always will, but it is much more controlled now, and when viewing the tank, you don't really notice it. So now it is time for more coral
