Hello all. I decided to get a blue tang, the so-called "ich magnet." The question I have is, what do I do about the ich. I have a ultraviolet sterilizer and the tank water quality is pretty good. I have some nitrates and the nitrites are at zero. My ammonia is up just a tiny bit since I did a tank shift. I want to say it is around .10. I even have a cleaner wrasse in there, but the tang has plenty of ich growing. What do I do about the ich? I have an anemone in there as well so copper is a no-no. Any suggestions or do I just wait it out. I have only had the tang for a week. I also noticed my puffer has just a few pieces of ich on it as well, but nothing serious.
