[Go to any local Albertsons and they'll have Mrs. Ball's pickling lime. If you can't find that, go to any Petco or other LFS and get a jar of Kalkwasser - a bit more expensive, but all the same chemically speaking. Then, go to any local pharmacy like CVS, Walgreens, etc. and tell them you need a syringe/needle combo - probably about $.35c each. They'll probably smirk and try to talk you out of it thinking you're a drug addict, but be persistent and tell them what' it's for - even if they laugh, be persistent. If that doesn't work, try your local veterinarian. When you get all the supplies together, mix up a slurry of the lime and some RO/DI water until it's a toothpaste consistency. Then, load the syringe and slowly inject some of the paste near the "mouth" of the aiptasia - it will ingest the paste, curl up and withdraw into the nearest hole, never to be seen again (hopefully!). These things breed like rabbits, so you may have to do this repeatedly until the population is under control. The idea that you can eliminate them permanently is unfortunately more wishful thinking than reality. Good luck!]
