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.
