I have used the foggers alot and they always crap out. For good reliable fog I use a modified humidifier. And if you are going to use a fogger with frogs, cover it as it can hurt the frogs, also dont use RO water for frogs as it will osmos through their skin too much!!!!! they will retain too much water and get sick and die. I recommend spring water, bought is good but I get it from a local spring out in the boonies.
