i recently [thought] that i successfully removed all my pulsating xenia, but a few weeks ago i noticed tiny little heads popping back into action. i have been meaning to do something about it, but never did.. until now. i am only noticing it in one area, so hopefully i did kill it in the other areas. (lets hope)
my question is what kind of caulking (reef safe) should i use to cover it up and suffocate/kill it? i have read that people have done this for an easy-out. or if not caulk, what?
thanks,
Corey
