one solution is to raise the temperature to 85 degrees SLOWLY and it will get to where the bugs(ICK) will not be able to tolerate the heat so they will die. leave it at 85 for about a week or two and you will see a difference. we have done that. it did go away in about a week so we left it at 85 for another week until it was finally gone. and have been ick free for about a month and a half... hope this helps. corals, anenomes, and livestock will be fine.
