A 50-watt heater that is set to 78 degrees Fahrenheit at the factory, for aquariums up to 20 gallons. There is nothing to adjust. The maker says it holds 78 degrees within one degree either way. It is fully submersible and comes with suction cups, so it can sit upright or on its side. A red light comes on while it is heating, and the maker says it switches itself off if it overheats. It is about 7 inches long and weighs 7 ounces. The shop sells the 50-watt size only. Let the heater sit in the water for half an hour before plugging it in, and unplug it before any water change.
