With the thermostat probe in the right spot, your thermometer probe shouldn't have to go under the substrate at all. most people use an infrared or laser thermometer to take floor temps. most probes are free floating, you never want to use anything sticky inside your tank. some thermometers come with suction cups that you can use to attach the probe to the glass, otherwise it just kinda hangs there.
