check the care sheet here on forum and go with that regarding temps and humidity, it may be ok to spray once a day, but may be not, you need to monitor the conditions. for water, use treated tap with water conditioner for frogs or any really would do, currently I'm using Prime, this way it is less expensive and safer too.
what type of bedding are you using? to change it all once a month and spot clean when needs to be is sufficient.

oh and welcome to the frog forum!
