Ugly is a little harsh. I wouldn't go through the trouble of nuking the rock to get rid of them, then all you end up with is a bunch of base rock. Coral eating fish are one answer, and I'm sure most Butterfly fish will do the job but any other corals are fair game also. I'm sure there must be someone close by who would gladly trade you some bare live rock for your rock covered in Zoas, I know I would.
