I've gotten in to do some work 3 times in the last week, starting to get "caught up" on the things I've been meaning to do. Went on a rampage with the aiptasia x, mostly on the (blue) cloves from hell. But I did have a handful lingering aiptasia here and there. I removed the last rock that had more than a few on it. They were really big! It turns out aiptasia x works well on the blue cloves. I just kinda puddle it on top of them and let it sit for an hour or so with the vortechs off. I then siphon out any left over puddles before turning on pumps. I also put fresh carbon in my bag to absorb any nasties from dead cloves. It takes a couple days, but seems to work pretty well. I assume kalk paste would work as well, but happen to have aiptasia x on hand.
