- Durable Quartz Fish Tank Heater: This aquarium heater is built with quartz heating rods that deliver fast, even, and efficient heat transfer. Its heat-resistant ABS shell and controller provide reliable performance, safe operation, and long-lasting durability.
- Advanced Safety Protection Systerm: The built-in anti-dry and overheat protection keeps your aquarium safe. If the water temperature rapidly exceeds 95°F / 35°C, the LED screen flashes “EE”and stops heating automatically; if the fish heater is not fully submerged, it displays “Er.” These smart alerts help prevent damage and maintain a stable, comfortable environment for your fish.
- Intelligent Constant Temperature Control: The fish tank heater automatically maintains a steady water temperature; When the temperature drops 1°F below the set value, it automatically starts heating again until it returns to the target temperature, maintaining stable warmth at all times. Ensuring consistent comfort for your fish.
- Easy & Secure Temperature Adjustment: Adjust the water temperature effortlessly using the external controller. Long press the lock button for 1–3 seconds to enter setting mode, then press the temperature button—each press adjusts by 1°F/°C (range: 59°F–94°F / 15°C–34°C). The system automatically locks after 3 seconds of inactivity to prevent accidental changes.
- Warm Tips for Safe Use: Please always fully submerge the heater before powering on and ensure proper water circulation. Allow it to cool in water for 15–30 minutes after turning off to prevent the residual temperature melting shell. For any questions or support, please feel free to contact us.
