**Stupid question I need to ask**

Yes you can.

And as a sidenote, letting water "sit" may remove chlorine, but if you have chloramine in your water, it will not evaporate.

I don't see why it's important though, I didn't realize it would harm the snake.

Chlorine evaporates fast - in less than ten minutes.

Either way, at normal drinking water levels, it won't harm your snake.
