I know I understand that but my uth is not hot at all, thats why my faunarium is only about 73 (the hot side). When I said I went over the top, I did put a lot in and you said about 1/4 of an inch is good so I've checked, shes very safe because the floor really isn't hot at all. But tomorrow I'm going to get a better uth and put some more bark in to be safe. I assure you, I wouldn't put her in any danger.
