Hey!

I recently moved my tubs to a different place and since then cant get temperature right in of of the tubs .

The bottom of the tub isnt perfectly straight so i taped the mat on the bottom + add some bits of polystyrene so the mat is in contact with the bottom of the tub everywhere (40% of the tub )

When set up for first time the gun was reading same temperature as the thermostat so it was all fine , but the next day and since then the temperatures go bananas for same reason so i play with it again for a bit and its fine for majority of the day but its like something always happened overnight ...

New thermostat is on the way , bu i thought maybe im doing something else wrong ?

Any tips how to properly heat uneven tub please ? They are just on the shelf its not a proper snake rack just the store like one .
