I am the proud owner of a 6" nose to vent female pixie frog. My son got her for me for mothers day last year as a froglet. As of a couple weeks from now I will also be the proud owner of a new house.

In the entry way of the home (inside) there is an atrium. It is not enclosed by glass or anything. It is open to the rest of the house. The space is 8'x8' square. The under ground part of this atrium is fully enclosed by a concrete vault and vapor/moisture/radon barrier. It is 6 feet deep. It has a watering system on a timer which is connected to a municipal water source. It also has electrical outlets and a hose bib in there. It presently has 6 feet of 30 year old potting soil and an old ficus tree growing in it.

My plan, and this is what I need some back up from others on, is to empty the planter/atrium out and discard the ficus tree and the old potting soil. I want to replace the old soil with new soil so I know it has no chemicals in it and inspect the vapor barrier. I will be having an additional skylight installed (it has transom windows all around right now) and replace the ficus with a bonsai lime tree. I wanted to refill the planter with less soil than it has now so there would be about an 8" ledge between the atrium soil elevation and the elevation of the rest of the house. I wanted to install a soaking pond under the tree and have it attached to the water system for the tree. Was going to screw one of those faucet water filters to the system to dechlorinate the water. I then want to allow my ABF to live freely in this large indoor planter. Am I crazy? Is there anything I'm not thinking about here which would make this a really bad idea? I'd love to hear any insights and anything anyone has before I do something really stupid. In my head I see a froggy paradise. I want to make sure it doesn't turn into froggy death chamber

Additional info: We live in the AZ desert
our home is kept at 78-80 in the summer and about 74-76 in the winter
Just had the water tested and our municipal chlorine levels are "low" and we have very little copper, no iron in our water.
Frog eats frozen thawed mice, canned crickets and night-crawlers from a forceps
I have 3 chihuahuas who I think would leave the frog alone. We have the Sonoran Desert Toads out here so we train our dogs to leave anything amphibian alone and they do.
