Some clove polyps hitchhiked into my tank somehow. They are isolated to a small are about the size of a half dollar on a movable top rock. I have contulinously removed them by removing the rock and brushing them off with a toothbrush destroying the polyps under running water. I don’t do this in my tank. How the heck do I kill these dudes so they don’t come back and spread?
