Hi all , I took a look in my tank and I seen two growths of aiptasia near zoas on a rock , I am going to remove the rock scrape it and hit the spots with boiling water then thouraly rinse the rock before I add it back in the tank . My question is what are the chances the aiptasia will destroy my tank how can I be pro active , and ps I just bought this rock two weeks ago so that's as long as it's been in my tank
