Hi,

Right now i have the probe of my herpstat inside the tub, flat on the tub.

But since it's more consistant to put the probe on the heat tape, i figure i should compensate for the difference (on heat tape vs on tub inside)

Exactly how many degrees do you dial up for the compensation? I want to keep a hot spot of 90 degree ideally.

PS: i use flexwatt and sterilite shoe box tubs

Thanks you guys
