Whites Tree Frogs - Water

Question
QUESTION: Hi, I just got a White's tree frog yesterday and I was wondering what the best
kind of water to use is for when I mist him and fill his water bowl.  I have been
using spring water, but I was wondering if tap or distilled would be better?  
Thanks

ANSWER: Hi Brian, The easiest, cheapest and safest option would be tap water that has been treated with a dechlorinator. I'm a bit distrustful of bottled "spring water" because there is very little regulation in the industry. In Canada anyway, bottled water is merely filtered tap water. Distilled water is unnessesary and because the mineral content is missing it can cause problems for your frog due to osmosis. Frogs  are sensitive to both chlorine and the more stable chloramine, both are often present in municipal water. Water conditioners sold for fish (fish are very sensitive to these compounds) work very well to remove these. I treat a gallon at a time in a plastic jug and use that for the frog water. The brand that I use is called "Prime" but there are numerous options in aquarium stores. Some have "stress coat" which is aloe added to the conditioner. It serves some purpose for fish but I avoid those ones for my frogs.

QUESTION: Thanks.  One more question:  I have a driftwood branch thing in his tank and
today I realized that it has grow white fuzzy mold along the bottom due to the
high humidity.  What should I do about this?

Answer
Hi Brian, Removing the wood for a few days and letting it dry out is the safest way to get rid of the mold. You can speed up the process by baking the driftwood in a low temp. oven (200F) for around 20 minutes.
If you are getting mold growth then it sounds like your humidity is higher then it needs to be for a White's. White's have much thicker skin then most other frog species and can easily tolerate much drier conditions as long as they have access to a water dish. Keeping the cage too humid can encourage mold, fungal and bacterial growth which can cause illness in frogs. A light misting no more then once a day is fine for white's.
