So Stinkin Confused!!! (tank related!)

[snakesRkewl]

But if not tape, then how else are people keeping the probe in the right place? I've seen a guide using hot glue, but what if I want to take everything out of the tank for cleaning?

...sorry this is probably a pretty dumb question, haha. I hope someone can point me in the right direction.

Not a dumb question at all.
Just bury the wire and the probe under the substrate, the probe gets moved then you will notice it when you check the temps and place it back where it belongs.

Permanently gluing or affixing the thermometer probe makes it difficult to clean unless you want to re-glue it over and over each cleaning.
