So, because I live in an apartment and I'm not sure how long I will stay there, I'm not sure if installing an RO Unit is the best option. I can get distilled water at Wal-Mart for less than a dollar per gallon. Since I'm only going to have a few frogs to start with, that should last me a while. Unless, RO water is better for the frogs, then I need to know where to get it. Also, does anyone know how much it would cost?

Can I just continue to mist with distilled, or should I switch to RO Water?
Where can I purchase RO water and for how much?

Are there any inexpensive RO units I can purchase that I can store away when I don't need to use it and is easy to set up when I do need to use it?

Thanks guys.
