I have the lamp and under tank heater on right now. The bulb is 75 watt, and the UTH is zoo med's small size for tanks 10-15 gallons. (My tank is 10 gallons).

The temperature is at 86 degrees F right now. If I turn the lamp off for night time, will the UTH be enough to heat it? My substrate is also about 3 inches deep, and I know I need to take some out because it's pretty deep, but that will have to wait until tomorrow because I need to go home and the BP is living at my boyfriend's house until saturday. The substrate is eco earth coconut fiber if that makes any difference.

I really think the light should be off at night to make a night time setting for the snake (and my boyfriend ), but will the temperature drop too much?
