American Toad Water?

[UncleChester]

I can't get de chlorinated water for my toad cause my parents think it's silly,..

A dechlorinator is pretty cheap. The small bottle yoshimi linked to is only $3 and will condition 5 gallons of water. If your toad just has a little water dish, 5 gallons is quite a few refills. The larger bottles will be more economical. You'll probably pay more at a local petshop, but several months supply won't set you back much.

..but the toad never goes into her water like a day after a refill it so chlorine evaporates, but...

If you are unable to get a dechlorinator or collect rainwater, please at least let the water sit for a day outside of your toads cage for 24 hours before you refill it's dish.

It's not supposed to rain until tomorrow. How long does it take for the chlorine to kill toads? Lola (My toad) has been using sink water for a year now... is she doomed? Or does she still have time if she has clean water tomorrow?

Your toad almost surely isn't doomed. How long it takes for a problem to develop (if one even will) is dependent on too many variables that no one here could possibly predict what will happen to your toad. You've used the tap water for a year, a few more days will be minor. For the long term health, conditioning the water is the safest approach.

You haven't actually mentioned if your water is from a city or town supply? Or if you're in the country, are you on a well or spring?
