Try the position first before adjusting wattage- but you need those digital probe thermometers - those are crucial -- once you get the surface basking temps then we will go from thereHi there and thanks for the info. The watt is 75. If I am remembering correctly, I had got him a bigger watt because the past watt (50-55) was not warming him up after being under it for 30 mins to an hour. Should I go back down? I have moved his light since (away from the rock so hes not closer to it)
