I just bought a Zoo-Med repti therm UTH for a 10-20 gallon tank . when i fist clogged it in it was in the mid 80s-low 90's I checked the temp a minute ago and im up to 102.2 degrees!!!! my Gecko is still hanging out on the hot side too. For now I am just going to unplug it, when the tank was not heated it ranged betweem 73-82 degrees I feel no heat is being better than getting cooked alive. Anyone know how and can tell me how to get this better thermal regulated so my pal isnt cooked alive? He doesnt seem to mind it he came out of the hot side to hunt down a cricket and went straigth back, but im worried any ideas?
