Hey, Thanks for your help, Carlos.

I will definitely not put it in unless someone else tells me otherwise--- so next time I do get new branches, what should I clean them with? Just hot water? And if so, how do I keep them from growing moss? Or is the moss good for the frogs? We took the brach/log out because it seemed to be the source of an oily film that was over the top of my water. Every time we put the log back in, the oil went back on the water. I didn't think that it could be good for my frog...
