You are correct in thinking the hognose snake gets his minerals from his food and not his water. The variety of minerals in his normal diet far surpasses any minerals that he might get from water. Much of wild hognose snakes water is soaked up by body
in contact with moisture and no minerals acquired. I used distilled water for several years because evaporation leaves no scale in the watering device ; a plus unless you are using disposable cups.
