[Compact & Low Water Level] The mini heater features a compact and exquisite design with a wide range of applications. It is suitable for various aquarium sizes commonly used in homes (30cm/45cm/60cm). The safety water level is as low as 4cm, providing a safe and comfortable living environment for all aquarium inhabitants (fish, turtles, etc.).

[Multiple Safety Features] Equipped with multiple safety features including: anti-dry burning protection when removed from water, abnormal heating detection, overheating power cut-off protection, IP68 waterproof rating, and automatic constant temperature function. This mini aquarium heater provides comprehensive protection for the safety of aquarium animals. The heating element is made of excellent quartz glass material, which offers superior insulation even in high-temperature environments during use. Tropical fish, bettas, amphibians, and turtles in your aquarium are fully protected, ensuring safe and secure use.

[PID Chip & Smart Water Temperature Management] The mini heater is equipped with a built-in PID chip to achieve frequency conversion functionality. It rapidly heats the water to the set temperature at maximum power when first activated. As the water temperature approaches the set point, the heating power gradually decreases. Once the set temperature is reached, it maintains the temperature at low power, providing a safe and comfortable living environment for fish in all conditions. The heating power instantly changes based on the aquarium's water temperature, achieving energy savings.

[Protective Design] The protective shells on both sides of the aquarium heater are made of heat-resistant ABS material and are detachable. This design protects the fish from being injured by the heating rod. It also makes cleaning convenient and extends the product's lifespan. Please note that internal precision parts may be damaged during transportation. If the heater you purchased does not function normally within 1 to 15 days, please contact us immediately. We will resolve the issue as quickly as possible.
