Hygger Aquarium Heater with LED Controller and Auto Shut Off Protection

Product Description: Temperature Protection and Tips - The heater has over temperature protection. It will automatically stop heating when the water temperature exceeds 95℉. This is indicated by the LED flashing "HH" and a beeping sound. It will resume heating once the water temperature drops below 93℉. - Additionally, the heater has low temperature protection. It will start heating when the current water temperature is 1°F/1°C below the set temperature.

Warm Tips: 1. Ensure that the heater is fully submerged in water and avoid burying it in sand or exposing it to air dry burning. 2. When you need to stop the heater, disconnect the power socket and wait for 15 minutes before changing the water or removing the heater. 3. The external temperature controller is not waterproof. Therefore, it must be kept away from the water. 4. Installing the heater underwater near the water intake is recommended. It can be placed vertically or horizontally, with the vertical placement being space-efficient. 5. To promote even heat distribution, use a wave maker or circulating pump for the fish tank. Good water circulation helps distribute the heat generated by the heater. 6. Regularly clean the heating plate to maintain heating efficiency. Impurities on the heating plate can reduce its effectiveness.
