Caulerpa taking over frag tank

[maroun.c]

Caulerpa made its way to frag tank and taking over, cleaned up manually for hours a couple of time and it keeps coming back, I can move the Corals to qt and bleach the tank and restart, but how to deal with frags and colonies where it has encrusted? Added a sailfin tang but he's clearly not touching it.
Would dipping inhydrogen peroxide affect caulerpa same as algae?
Freshwater dip for coral who can take it like Zoas?
Fluconazole?
Any fish guaranteed to eat caulerpa?

Try a foxface... Some will eat it, some won't.
