Fully submersible heater

The aquarium quartz heater must be fully submerged to work properly.

Rapid thermal accumulation

The heating rod is made of explosion-proof quartz glass and a high-temperature resistant nickel-chromium heating wire with silicon carbide heat conduction; this results in faster water heating and a safer, more durable, long-lasting quartz heater.

External temperature display

The LED digital display screen shows the default setting of Fahrenheit for the current water temperature and the preset temperature. Every touch changes the set temperature by 1 °F. LED light indicates shows the heating status.

Precise temperature control

Adjustable temperature from 59 °F-93 °F to maintain a constant and stable temperature for fresh or marine aquariums.

Auto power off and warning signal

When the heating rod is exposed to air, the submersible heater will shut off automatically and emit a warning signal. When the heating rod is completely immersed in water, it will start working again.

A high-temperature resistant safety cover

High-quality and high-temperature-resistant PC plastic covers prevent fish from being harmed.

Directions for Use

1. Please unplug the heater and let it cool for 15 minutes first before you perform a water change or take out the heater rod.
2. The heater must be fully submerged underwater for at least 5 inches.
3. Keep water in circulation for better distribution of the heat.
4. It’s essential to keep it off the gravel or sand as the difference in heat conductivity between the water and substrate could result in the heater glass cracking.

  1. Lavs Snails

    This is really a wonderful heater for any home aquarium! The heating element itself blends well into the background of the tank and is virtually invisible. The display which hangs outside the tank is large enough print to see far away but not too large that’s it’s intrusive. It really holds and maintains the temperature extremely well! Our boiler was on the fritz for a day during a 10°f night and this heater preformed above and beyond the others I have in various other tanks. Really a wonderful heater and will be getting more for my other tanks!
