I have a 100g tank about a year old. I have a cortez ray, a lionfish, and a leopard shark. I some live rock throughout the tank. I recently have had problems with ich. My parameters are fine, but it seems everytime I add a new fish, they get it and die, but my other guys don't get infected. I added a huma huma and another trigger, and they both died within 3 weeks. Does ich stick around my rocks, and if so what can I do? My uv sterilizer has gone bad and has been down for 5 months. Could this be my problem? I am in the process of getting a new one. If ich does stay on the rocks, would a ich treatment and water change cure this?
