Use the towel as a emergency heat saving method and not as a permanent solution. Please forgo the strabucks for a week or cut back on something similar then go out and get a good quality submersible aquarium heater. You should expect to spend $15 - $40 for a aquarium heater. Also remeber when locating an aquarium never place it where it is drafty or the tempature in the room has major fluctuations.
