Sorry to hear. My LPS never seemed to mind, Duncans, torches etc. But my flatworms never seemed to mind either.Quick update about some side effects... Since the day of dosing a few Lps corals have not opened up, some are now showing skeleton. My 3 year old orange lobo the size of a large grapefruit has been deflated since dosing day and now has skeleton coming through the flesh - never good. Elegance still has not opened fully, and one scoly out of 4 is deflated with skeleton poking through. Acro PE still not as great as it was prior to dosing. Not sure if and how they are related, just posting observations.
