Reptile Water 

Reptile Water Supplies neutralizes harmful chlorine, chloramines and heavy metals, such as copper, iron and zinc, in tap water. Also contains unique colloids that protect skin (for applicable species including turtles). Can be used with aquatic turtles, amphibians, snakes, lizards and all ornamental fish.

It's ideal to utilize the spring water sold in bottles, as opposed to spring water that might go through your tap, as the packaged stuff is more predictable in quality. This sort of spring water is for the most part protected use for reptiles and amphibians to drink without being treated for chlorine or chloramines.
