For those of you that use probes under your tubs, how do you titrate it to be 90 in the tub?
I'm waiting on my IR temp gun to come, so that's not an option yet. I used to keep the probe on the inside bottom of tub to ensure its 90, but read a few horror stories about snakes getting tangled up.
Should I set the thermostat to 91-92 to compensate for the layer of plastic? Orrrrrr?
