  • 【Two-Stage Adjustable Power Design】The adjustable power heater allows you to switch between 400W and 800W heater power. Use low power for small fish tanks and high power for large fish tanks; use low power in spring and summer and high power in autumn and winter. This aquarium heater can meet the needs of different seasons and different sizes of fish tanks.
  • 【LED Digital Display Controller】The external IC temperature controller for the aquarium heater displays water temperature, set temperature, current operating power, set power, and all error codes. The digital LED display shows the current water temperature and preset temperature (in Fahrenheit), as well as other features such as minimum and maximum temperature display (low/high) and automatic shutdown in case of low water levels. The external controller makes setup and operation more convenient. Each touch adjusts the set temperature by 1 Fahrenheit (1°C).
  • 【Comprehensive Protection】 Over-Temperature Protection: When the water temperature exceeds 94°F (35°C), the heater will automatically shut off and emit a buzzer alarm, while the controller will display ‘’HH’’. Low-Temperature Protection: When the water temperature drops below 59°F (15°C), the heater will emit a low-temperature alarm and display the error code ‘’LL’’. Water Shortage Warning: When the quartz aquarium heater is not fully submerged in water, it will flash ‘’Auto Shut-Off’’ and automatically stop heating.
  • 【Dual Temperature Control System & Memory Function】This aquarium heater uses a dual temperature control system. When one temperature control system fails, the other temperature control system starts up. This prevents fish from being cooked by high temperatures and is safer. Temperature adjustment range: 63-94℉, and it has a memory function. When power is restored after a power outage, the adjustable power heater will retain the temperature setting.
  • 【Material & Double Quartz Tube Design】The heating rod is made of explosion-proof quartz glass and high-temperature resistant nickel-chromium heating wire, while the heat conductor is made of silicon carbide. The double quartz tube design allows for faster water heating, and the thickened high-temperature resistant black ABS shell increases durability.
