I spot kill mine with aptasia x. Peppermint shrimp are hit and miss. Nudibrancs are hard to come by and not worth it to kill a couple. Some people use vinegar or aptasia x which is just kalkwasser.

I don't think aptasia x is all kalkwasser. Joe juice is. Just one aptasia x should be easy to take care of using AX or JJ. Nuke it!

Got my friend going to get me a needle so I can inject them . Wanted to start dosing vinegar anyways now that I beat cyano

I keep a filefish. They might eat zoos, but even though there is aiptasia in my overflow, there is not a single one in the tank.

If you just have a few kalk paste and a plastic syringe will work fine.

Is this thing only on one rock? Dude, save yourself months worth of sadness and headache and take that entire rock out. Let it dry out for 6 weeks (or however long it takes to be bone dry) or boil it for an hour. Injecting it with any of those chemicals is just going to make it worse in the long run. Also you said you noticed that it moved, every cm that it moves across your rock it leaves a dozen tiny bits of itself behind (they're called pedal lacerations), and each one will sprout in to a teeny tiny little aiptasia. That rock is likely infested with them by now, only they're all too small for you to see.

No single piece of live rock, especially a sump piece, is worth risking those things taking over your entire tank. If you search forums you'll find that next to ich, aiptasia are probably the biggest marine aquarium scourge. In the allopathic battle between aiptasia and everything else that you actually paid for, aiptasia always wins. They'll pop up right in the middle of zoa colonies and eventually kill them, they cause tissue recession on any LPS or SPS that touches them, and they sting the heck out of clam mantles.

Chances that you'll kill the thing completely with an injectable (acid, joe's juice, kalk paste, what have you.) are very low and in the process it will likely release thousands of microscopic planula in to the water column that will settle on everything and start to grow new aiptasia. Further more, if you can see one on that rock, there's most certainly a dozen more that you just can't see yet. They can and will reproduce faster than you can kill them, and they will find places to grow in your tank that you'll never be able to reach with any syringe or tool you can buy for working with a tank.

If this is something that can be nipped in the bud simply by removing that rock and sterilizing it, you should consider yourself lucky.
