• How do I reset the local time on my Hygger 24/7 LED light?

  For many models like the HG-999, long-press the gear/settings button for about 3 seconds until the time on the screen flashes. Use the up and down buttons to adjust the hour and minutes, pressing the gear button to confirm each selection.

• Why is the temperature on my Hygger heater display different from my thermometer?

  Water temperature can vary in different parts of the tank due to circulation. Hygger recommends placing the heater in an area with good water flow and ensuring the separate thermal detector is fully submerged but kept away from the heating element itself for accurate readings.

• What should I do if my Hygger light falls into the water?

  Immediately unplug the light from the power outlet before attempting to retrieve it. Do not reuse the light if the electrical components have become wet or if the cord is damaged.

• How do I contact Hygger customer support?

  You can reach Hygger support via email at service@hygger-online.com for troubleshooting, warranty claims, or product suggestions.
