I understand this is an old post, but find it a really fascinating one (seeing as how often I've had it in my QT tanks... AND my display ones. Hah. Whoops. =/
I've used salt and heat with great results before, but also have worked for a fish lab that always used QuICK cure on its wild stock. That being said, these were not tanks that needed to look pretty - staining was just ignored, and the fish seemed to be cured quickly (which, for already stressed stock, could be arguably more important than anything else).
I'm really intrigued by Ich Attack and other methods of treating ich. For instance, I have to imagine that wild fish must have a way of defending themselves from ich infestations - coevolution doesn't really favor diseases that kill the host, anyhow. Ich attack intrigues me because they mention that you can dose it as a preventative treatment (which may be useful for when that rare fish shows up at the LFS... and looks healthy, but is swimming with some potentially diseased looking folk). It also says that it's safe for inverts, very appealing to me (a rash of snails rotting in my substrate is the last thing I need).
But on the other hand, what do people think of having high heat and vacuuming the gravel extensively, frequently? As the organism goes through its life stages, would a strong immune system and constant physical removal of the organisms be enough to stave off a bad infestation, for example?
