take it out, cover it with lime/lemon juice & then burn it with a lighter. there's no such thing as going overkill when it comes to aiptasia. I took my rock out & melted the aiptasia into basically liquid and it still is coming back!
honestly if you can afford to take the rock out & leave it out without a cycle or coral placement problem, just nuke the thing.. cover the infected area with a kalkwasser paste(think of that paste glue kids use to make art projects in elementary school) and then boil the rock the following day. that should solve any issues you have.
