1. The tape is holding The UTH to the glass, but is not in the enclosure, correct?
2. I use printless newspaper but it is harder to maintain humidity than some other substrates.
However. It is much easier to keep clean.
There will be a difference between what the probe reeds and what is the temp in the tank.
It should be consistent (hopefully). For example if it reads 93 at the probe and is 88 in the tank, you know you are 5 degrees off and can adjust accordingly.
Urine tends to smell, but probably not terrible with a small BCI. It’s also yellow.
Very important to keep the tank CLEAN!
