Hey all! I have a UTH that I do not think is cutting the mustard. I have ordered a thermostat online, but it has yet to arrive. I checked my digital thermometer in the enclosure this morning, and it was down to 78! During the day it gets up to around 80. I know a thermostat will keep the tank from getting too hot, but it won't make the heat pad get hotter right? How am I supposed to keep the enclosure warmer without using a heat lamp? I have a heat lamp that came with the tank, but from what I understand the heat lamp should be unnecessary with the UTH. I know that they have bigger sizes of UTH, but I have a 20 gallon tank, and the larger ones would seem to be too large.
