Why You’ll Love It
The hygger 106 Hollow quartz heater intuitively displays the current water temperature, heating state, and the real-time power. You can preset the target temperature and adjust the temperature from 59℉ to 93℉ easily. The memory function will be restored to the temperature you set when the power comes back, and no need to reset. It is ideal for freshwater and saltwater aquariums of 50–300 gallons.
Key Features
Advanced Heating Technology
The HG106 hollow quartz heater utilizes dual tube quartz glass material and high-temperature resistant nickel-chromium heating wire, ensuring more uniform and efficient heating.

The quartz heating element is designed to auto-stop when the water temperature reaches the set point, and it will automatically restart if the temperature falls 1°F below the set level.
Low Water Alarm
The hollow quartz heater is equipped with a dual-sensing probe that efficiently detects when there is no water or the water level is below the top of the heating unit. In such cases, it automatically shuts off the heater and activates a beeping alarm to alert you of the abnormal state, ensuring the safety of the aquatic pets.

Safety Feature with Memory Function
It has a memory function that automatically restores the set temperature when power is resumed. It will begin heating to the pre-set temperature automatically.
External Temperature Controller
The heater is accompanied by a hanging controller featuring a large LCD digital display, which clearly shows the current water temperature and real-time power status. A red indicator light provides real-time feedback on the heating state.

Overheating Protection
It is equipped with an over-temperature protection system. The safety alarm is activated if the water temperature falls outside the measurable range, and it will automatically shut off and display an ‘HH’ code alarm when the temperature exceeds 95°F. Conversely, if the temperature drops below 59°F, it will display an ‘LL’ code alarm and automatically begin heating to the preset temperature.
Usage Tips

1. Secure Mounting: Utilize two strong suction cups to firmly attach the heater to the side of the tank, ensuring the heating element is fully submerged at least 2 inches underwater.
2. Proper Orientation: Position the heater so the top faces upwards, allowing the probe to sense the water level accurately.
3. Safety and Efficiency: The ABS guard shield features an irregular, hollowed-out design that aids in better diffusing and heating the water.

Awesome costumer service and good product that’s why I keep coming back 🙂 Thanks!
This is a pretty nice heater. It is well made, and controls temperatures well enough. I like that there is not any glass present to break into the tank if it were to fail. Not much to discuss other than it is really nice.
A great heater for my discus fish, it is a part of the appealing in my tank
