From now on all people MUST only drink water no carbinated drinks ... they're not good for you after all and your body doesn't "need" carbonation or use regular gasoline all cars will "run" on it ... some of the higher compression sport cars will just ping and run like crap.

Huh?

I would expect that certain types of fish would benefit from the addition of salt and other minerals, surely. But I have not used salt other than to treat ich, because my fish don't need it. There is some salt and other trace minerals in tap water... I don't need to add more. It would be more like providing air-conditionning to someone who lives in a temperature region where it never gets hotter than 85F, to use your analogy.
