And I always heard 90-94 was perfect for hot spot...
So for a tank using reptibark... should the probe be below the tank? Or inside the tank buried under the substrate?

And ultimately, is the temperature of the the heater what's important? Or the surface temperature of the substrate(Temp probe vs Temp gun)?
