+1; Aptasia X, Joe's Juice and Kalk paste are all essentially the same thing - concentrated lime; toxic to any living coral in your system in large enough amounts. If you're squirting/smearing it in and amongst zoas and don't kill off some of them in the process, you're lucky. Still the best method for removing api, but as Kraylen said, it will kill zoas, mushrooms etc. if taken in by the coral.
