Some quick tank questions

[NH93]

You want to put the probe near the top of the substrate, so it captures the heat of the ground the snake will be touching. What is your substrate? That may take an affect. Ps make sure the probe is not sitting on top. Just near the top.

Some, such as myself, disagree with this. I like to keep my probes on the bottom of the vive; the hottest point where my snakes can get to. I notice too that my ball python pushes the substrate all over the place, so if you have less substrate it makes sense to adhere it to the bottom rather than just placing it in the substrate where it can be moved around.

I have the UTH probe secured on the outside of the tank, in between the UTH and the vive. The thermometer probe as mentioned above is secured inside on the bottom of the vive.
