Maintenance
Proper maintenance ensures the longevity and efficient operation of your heater.
- Cleaning: Periodically clean the heater rod to remove algae or mineral buildup. Always unplug the heater and allow it to cool for 15 minutes before removing it from the tank for cleaning. Use a soft brush or cloth and aquarium-safe cleaning solutions if necessary.
- Water Changes: During water changes, ensure the heater remains fully submerged. If the water level drops below the heater, it will automatically shut off (displaying "ER"). Always unplug the heater before draining significant amounts of water.
- Inspection: Regularly check the heater's glass tube and power cord for any cracks, fraying, or other signs of wear or damage. Replace the heater if any damage is observed.
Troubleshooting
If you encounter issues with your hygger aquarium heater, refer to the following common problems and solutions:
| Error Code / Symptom | Description | Solution |
|---|---|---|
| "ER" displayed on controller | Heater is out of water or water level is too low (dry-run protection activated). | Ensure the heater is fully submerged in water. If the water level is low, add water to the tank. The heater will resume normal operation once fully submerged. |
| "EE" displayed on controller | Water temperature exceeds 97°F (overheat protection activated). | Check the ambient room temperature. If the tank is in a warm environment, consider moving it or using a chiller. The heater will stop heating until the temperature drops below the safety threshold. |
| Heater not heating | The red indicator light is off, and the water temperature is below the set point. | Check if the heater is plugged in correctly. Verify the set temperature is higher than the current water temperature. Ensure there are no error codes displayed. If issues persist, contact customer support. |
