Any ideas on this and how to control it? Its growing on the base of an acropora colony that had stn and is recovering. As far as I can see, this it the only place this is growing

Yup. You could try epoxying over them.

I just fragged the living tissue, remounted it to frag plugs and tossed the base. Don't want to take any chances
