a long time ago, i read that ick/ich becomes sterile at around 85 and cannot reproduce, and the high temps shortens their life cycle so they die quicker. A long time ago, i had an ick/ich outbreak and used this method and it cleared it right up. I haven't had an ick/ich outbreak in several years now, so I haven't had a chance to test it again. Is there any truth to the high temps making it unable to reproduce?
