Curious what you guys set your UTH temp to, those with tanks, specifically. I currently have mine set at 93 and I'm wondering if that is too low when you take into account the substrate.

I put down about an inch of aspen so this certainly acts as some insulation. I have heat bulbs that provide ambient air temp, this makes the surface about 90 on the hot side, however its a few degrees cooler in the hide because its blocking the heat from above.

So I'd like to bump up the thermostat for the UTH up a bit which is right under the hide, but don't want to go too high and risk a burn should he decide to dig down and get directly on the glass.
