yeah I figured that the temps on the mat itself would be a little higher, so I make sure that the temp reads around 95 degrees. Does anyone else know if 95 degrees on the mat itself should make it good enough in the cage orrr?? I initially had both of the probes on the inside of the tank but the areptitemp 500R's wire was wayyyyy to big to cover up good enough and it was just wayy easier to put on the under side of the UTH itself. But like I said it reads 95 degrees.
