I didn't read this whole thread, so forgive me if this was brought up, but have you tried a Copperband Butterfly? I had an outbreak, tried all the "juices" and couldn't reach spots to apply the superglue method. I ended up finding a CBB that was eating frozen at the LFS. Put it in QT and it continued to eat during that time. So in the display it went. It did take it about three weeks to discover it's appetite for the Aiptasia; but I haven't seen another Aiptasia in months. I've been lucky the CBB hasn't developed an appetite for corals....yet!!!
Just a suggestion, take it for what it's worth.
