The keeping them warm is the main thing I'm worried about. Might be because of the tank or I bought a faulty uth but it did nothing for the temps in her tank (currently unplugged since it was crap) and with my room at 70 degrees I can't get the cool side of her enclosure over 77 (hot side stays 88-90 with heat lamp). Does heat tape work better or did I just get a bad uth?
