Reverse Osmosis vs Distilled - And Other Water Questions

[flybyferns]

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.

Hello,
The article and information Amy gave you is very important

The distilled water is perfectly fine for misting and very important for automatic misting systems.
Distilled water will not leave water marks/ mineral build up on the interior glass of the enclosure.

Just curious...what species of frogs do you keep ?

Additional information can be provided once we know more about the specific species.
