Fluval Aquarium-Heizer E200 A773

Probably the most technologically advanced immersible aquarium heater of our days with the new VueTech technology.
Its LCD display provides peace of mind with its continuous real-time water temperature display. While the heater is in operation, the temperature display will change color if the water temperature deviates from the preset temperature. Should external heat sources or other equipment cause an excessive rise or fall in aquarium water temperature, the colored screen will begin flashing to indicate a potential risk.
