Three weeks ago I was trying to find ways to get rid of my aiptasia. I tried about 4 different peppermint shrimp and none of them wanted to eat aiptasia. So i got a copperband butterfly fish. He eats, but just not aiptasia. While researching the butterfly fish I stumbled across this article on the GARF website. Its talks about using pickling lime to kill aiptasia without harming anything else. I searched for two weeks but could not find any pickling lime any where in Austin. There were plenty of sites online. Today I went to Wal-Mart and found some.(its on the vacuum cleaner aisle)I followed the steps and it seems to be working. I sprayed about 12 aiptasia anemones and all of them took it and have not come back out. It really does seem to stick to them. I will not fully know if it works until a few days or weeks. But if it does I will let you know. Here is the site if you want to read it for yourself and try it. Killing Aiptasia. If you need to borrow some of the pickiling lime I have plenty.
