I found that joes juice coupled with Peppermint shrimp army works the best.
I had a few, some that i couldnt get to behind my stack, and I added 10 peppermints over a week period.
NO MORE AIPTASIA..
And If I see one pop up during the day, the next morning it is gone.
I think, and this is my opinion, aiptasia are a normal healthy part of a reef.
I know they are "nusiance" but in the wild I would bet lots of reefs have them , and critters eat off them.
So when I see one in my tank, I just chalk it up to a natural occurance, and a healthy system.. Then let my peppermints do the job, and Ill Nuke a couple if they are out in the open.
