Using a #18 syringe, inject Stop Aiptasia into the center of the Aiptasia disk at the base. The Aiptasia should turn dark in color and fall off the rock within 12 to 24 hours. They may then be removed from the tank. Many hobbyists report that their fish ate the Aiptasia after several days saving them the trouble of removing them by hand. Stop Aiptasia is safe for use with any medication present in your aquarium. Stop Aiptasia is safe when used as directed, but Chem-Marin is not responsible for any damage caused by misuse of its products. Stop Aiptasia should be shaken well before use and kept refrigerated.
