The goal is to get substrate surface temp to right about 92 right? so if its underneath the substrate then the acurite would probably read a little higher (depending on substrate). Do you actually stick your probe to the tub or just let it dangle in there (guess it doesnt matter if its under substrate)
Surface meaning the bottom of the tank, inside, under substrate.. Put the probe for thermometer against the glass on the bottom of the tub. The white does come off and stick.
