Ok I have a reptile basics iris wide with belly heat and a johnsons thermo. Now the problem is that the paper said to place the probe directly onto the heat tape but when I did that the temp inside the tub doesn't seem high enough on the hotspot. I even tried bumping up the temp a little and put a piece of plastic in between the probe and heat tape. I ordered a heat gun with everything but didn't get it cause it was on back order and now I am unsure of how to tell if it is hot enough. Is there something else I can do? Or does anyone have any suggestions???? Help Please!!!!
