"If you're worried about the chlorine and fluoride in tap water... Just fill a pitcher and let it sit for 24 hrs. All of that will evaporate."
Pretty sure it's bad to leave it out...not only will the Cl and F not evaporate (think of salt water, only the water evaporates leaving the salt behind - even if it was dissolved) plus mold spores/dust could get in the sitting water.
I used distilled water (you can get a gallon of it for like $0.50 at walmart) just in case cuz I have really hard water too. I was just too worried about what all the chemicals could do. I mean, too much chlorine could be bad for humans even...
I have received very stern warnings against giving them distilled water. It's not even that great for humans to drink too much. No electrolytes. Having stuff dissolved in your water is GOOD for you.
And chlorine is a gas at room temperature and so WILL evaporate out of the water. Idk about flourine. Salt won't even melt until about 700*(?) F. Very very high, so of course IT won't evaporate. Lrn2chemicals.
You can speed up that evaporation process by boiling the water for a few minutes, then keeping it wherever you're going to keep it, or letting it cool before giving it to your snake.
