Setting up a glass tank setup with a zoo med uth. I have heard so many different things from people but no clear answer. Where to I set the probe for the thermostat at? In between heat mat and glass? But then too much air bubbles will form and not heat correctly? If it is this was do I need the probe directly smuggled in the middle? Or should I put it inside the tank where it can be pushed off the heat mat so it will the over heat? 😂 please help a rookie out.
