Reverse Osmosis vs Distilled - And Other Water Questions

[FwoGiZ]

There is virtually no difference in distilled and RO water.
Distilled is 0 ppm...
RO is 2-10ppm...
both RO or Distilled water will NOT leave stains or clog misting nozzles.

EDIT: to make comparison... good quality tap water can be as low as 60ppm (in Canada ) it can be up to 200ppm too depending where you are. Well water is probably VERY high.
US usually has very poor water quality and can be 300-500ppm.
If you buy bottled water, check out the PPM rating (they HAVE TO specify in Canada... not in the US...!) if it says spring water, it can be 200-300ppm which is higher than most of Canadian tap water!!! Treat that tap water with chlorine thingy and let it sit for 24hr and you just dropped another 20-40ppm.
RO water can be found in most grocery store. "Reverse osmosis filtered water".. it will be 2-10ppm usually.
You can get 2-3$ TDS Meter on ebay if you wanna test water around you
Make sure you understand what TDS, PPM means. There is more to water quality then just that one stat.

there is some saying that distilled might be bad in the long run if you use it in a soaking bowl, that it would strip the animal of its minerals.
For dart frogs, that usually doesn't really apply as they won't soak or if they do, it will be in a vivarium where minerals get mixed to water anyways.
That would be different if we were talking about a pacman frog and it's water dish for say.

I don't think auratus are such good frog for someone starting in this hobby.
Tinct azureus and cobalt, along with Leucomelas are great frogs. You should consider phyllobates terribilis too!
