Vypyrz Tub Set-Up, The Basics...*DUW*

[MissDizzyBee]

I have a question. I just bought the same tub, how's your temps, because I can't get my cold side higher than 71-72. My hot side it fine.
I also wondered, are you allowed to put the probe in the tub under the hot hide, appose to under the tub and under the heat mat?
Wouldn't it be reading the temp a little different than what it would be if it were under the hide sitting on the bottom?
I'm very new to all this and need advice.

I use a smaller UTH on the cool side set to an appropriate temp.
