Man, I don't know how to say this without sounding like I am insulting your intelligence, but how did you not realize that regular tap water is bad for frogs? lol....I tend to file that one under common sense, especially for someone who keeps animals.

My grandma (71 years old) heard I had frogs again the other day and I was rinsing out their tubs and she yelled at me to make sure I treated their water. And she has never owned a frog or reptile in her life. She thinks they are gross and ugly. Even not being an enthusiast, she recognized that untreated tap water = bad for frogs. Theres no excuse for that kind of negligence in this day & age. There just isn't.
