"Clamping" Coral

[Garf]

I am after a list of the most problematic corals, that is the ones that are least likely to do well in an ATS system. If I can get one of these problem child's, I will be monitoring it's performance in my skimmer modified set up to see if it fairs any better than normal.

I would have to say that ORA Green Birdsnest has seemed to be my most problematic coral to keep. Not sure why. It struggled in the Doc's tank starting a few months into running the scrubber, it would clamp up 3-4 days in and open up the day after cleaning. Lost a baseball sized colony eventually, then in my personal tank with the UAS tester that one was volleyball sized and it got knocked out too.

Thanks Floyd, exactly the info I'm after.
