yep, there are three steps to provide good ich prevention:
-good heating
-some cooling
-healthy diet


the funny thing is that ich is much more of a problem in tanks then nature. in nature when a fish gets ich, it gets only a few spots and as they fall the fish keeps swimming and doesnt get reinfected. the problem in tanks is the same fish gets hurt over and over and over by more and more and more ich. but, in nature ich is a pretty successful parasite as it does minimal damage to the host in most cases.
