ok first of all - temps, in your other thread you said you don't have a measuring tool and you can just guess, so that you need to change, you need to know exact temps.
then water- change your water to treated tap water asap. you can use special water conditioners for frogs or any dechorinating products would do. I'm using Prime right now.
pic of the frog and it's enclosure would be helpful, are 3 sides covered? sometimes they feel stressed out being in open, some plants/hides would be useful.

how big is a frog?
