I recently took in a 4 year old albino BP and set up a temporary terrarium for it. I bought a Vivisun 20 gal UTH and a zoo med reptitherm thermostat. I put the probe between the glass and the uth and turned it on, with the setting at 90f. The temp with a thermal gun shows spikes of 97 degrees and the temp on the thermostat will reach 92-93, so I lowered the temp to 87, but the temp still gets to the 90s with the gun and the temp on the thermostat. I’m afraid I’m going to bake my new friend, so I’m currently heating her enclosure with an overhead light. Is there something I’m not seeing here? I started off with the zoo med uth, but it never got warm at all, so I switched to the vivisun. Any help would be appreciated
