That being said, I have one of the original aiptasia zappers from Paul B (his name here on RC). It worked great for me on large aiptasia. I bought a few peppermints a day or 2 after first getting and using the aiptasia zapper, so they kept any new ones from popping up after melting away the big ones I zapped. I actually do still have 2 aiptasas in the corner overflow of my tank. I thought I'd eventually have to zap them and/or put one of the peppermints in there to get rid of them. Amazingly, it's been more than four years since then and they're both still in the corner overflow area and they've never moved are reproduced. There's no aipasia in my display, refugium, or sump. 4 years ago I was cetain those two aiptasia in the overflow wouldn't take long to cause another outbreak, but for some reason, that never happened and it's been more than 3 years since I've even had any peppermints in that tank. I think those 2 aiptasia are either sterile or have been spayed or neutered.
