The Eheim Thermocontrol E Fish Aquarium Heater is a fully submersible heater that works wonders in freshwater and saltwater aquariums. It features precise temperature adjustments and has dry-running protection, which provides control and safety when water levels or low or when other accidents occur. It’s also designed with a glass jacket that increases the heating surface and acts as a heat shield—this not only ensures optimum heat emission, but it also ensures uniform distribution around your underwater buddies’ tank. With zero readjustment required for accurate results, this heater includes a 5.5-foot-long plug-in cable, a double suction cup holder to secure it in place and a control lamp. When the lamp shows red, it means that it is heating up, and when the lamp shows green, it means that the temperature has been reached!
