back when I was a kid I saved maybe 30 frog eggs from a kiddie pool my dad was dumping out and put them in a 10g tank with some api or tetra (forget which was around then) dechlroinator. My tap was not ro, but I don't remember pH since I was a kid. I should note that house used well water. Anyways about 7 frogs made it to 'adult' age- 4 green treefrogs and 3 brown ones I think were wood frogs.
