I am sure there are dozens of posts about this but I can't find any-WATER question

Depending on where you live, most tap water in the U.S. is pretty safe. Though, I use either bottled water, or I use reptisafe, just as a precaution. If you drink the tap water, it's probably safe for your pet. Another way to dechlorinate water is just by leaving it sitting out in a gallon jug. This makes it easy, and if it's easy, why not just do it, just in case. Amphibians are much more sensitive to chlorine and other chemicals, and need the treatments to tap water regardless.
