Is this overkill on corals for a 20g ?

I agree with Flatlander. I think the bubble coral will be the worst culprit. I have stayed away from that sucker for the that very reason.

Frogspawn, I have the branching, so its not a big deal, I just cut off a branch. It actualy just recently divided into 4 heads.. woohoo.. and has a ton of little heads growing off the stalk.
