I took a more extreme approach when I noticed a few small aiptasia anemones in my tank... I took the rocks out of the tank and burned the aiptasia off with a lighter, and it worked great. Now, this method WILL kill off any desirable algeas or corals in the immediate area, but it works great if you have just a few aiptasia anemones that aren't right next to anything that you don't want to lose. Just my two cents... Hope it helps.
