Dechlorination
· If your water is only treated with chlorine, then letting it stand over night should allow the chlorine to evaporate from the water and make it safe to use. In fact, you can even speed this up by bubbling air through the water with an air stone. This will increase the surface area of the water and allow the chlorine to evaporate even faster.
