Fire bellied toad water question

You will need an aquatic section of the enclosure, or at least a container filled with water for your FBT's so you don't need to worry about humidity. Tap water is OK provided it is allowed to stand for a few days to get rid of the flouride that is added to it . Better still to use clean rainwater from a water but for both spraying your plants and for the toads to swim in.

The terrarium has a large water dish

While I agree that chlorine and the chloramines are not desirable. What is in you tap water is not going to cause any immediate or longterm harm if used occasionally straight from the tap. And as asked by the OP, a spray bottle that formerly contained tap water is not going to be any issue at all. Tap water is not a death sentence, but I agree not desirable for long term use.

I have a friend that brings me spring water for mine. If forced to use tap water i treat it with Exo Tera's Aquatize first and let it stand for a few hours first.
