the power here in the mountains used to go out during a heavy rainstorm let alone when it snowed lol, they had a faulty transformer that finally blew and took out the poles it was attached to, after replacing it the power here rarely goes out for more then a few min, but in case of longer power outages I usually light my fireplace and seal off all the other doors, I was wondering would having the fireplace lit using untreated wood be detrimental to frogs ? Cedar's tank is sitting on a wheeled cart so can move him around if necessary for cleaning etc and would be able to adjust how far away from the fireplace to keep his temps in the right range.
