Snappy: Thanks for the insight. This is actually my first coral, I am still waiting until I am sure that my system has stabilized and that I figure out the Ca, Mg, alk issues until I add coral.

I still have plenty of algae, now that I know what this ceature is I will have to be a bit more vigilant in pruning algae around its perimeter.

Any special feeding requirements I should be aware of?
