Hygger Mini Fish Tank Submersible Heater for Small Betta Aquarium

Introducing the hygger Mini Aquarium Submersible Heater! This immersion aquarium heater comes with an external temperature controller, beep alarm, fault prompt, and other great features to keep your fish tank at the perfect temperature.

Before using the heater, here are some important precautions to keep in mind: 1. Ensure that the heater is fully submerged in water and that the water level is sufficient. 2. Place the heater rod near the filter intake to ensure even circulation of warm water. 3. Always unplug the power supply before making any water changes to avoid dry burning and potential damage. 4. After unplugging, let the heater cool for at least 10 minutes before removing it from the water. 5. Avoid letting the heater come into contact with gravel or substrate to prevent cracking.

Our nano aquarium heater is equipped with safety features such as low water level shutdown and overheat protection. If the temperature control system detects a malfunction, it will sound an alarm and stop heating to prevent any damage or injury. Please note that although the power will automatically turn off in case of a malfunction, residual heat in the heating rod may melt the shell, so please handle it as soon as possible.

The hygger Mini Aquarium Submersible Heater has a sleek black look and a mini size that makes it easy to hide in your aquarium. The 50-watt Betta heater is designed with a 4" long x 1" high heating element that takes up very little space, making it perfect for 5~10 gallon small aquariums and shallow water turtle tanks.

With an adjustable temperature control, you can easily set the temperature between 59 and 93 degrees using the external thermostatic temperature controller. The digital display allows for intuitive viewing of the real-time water temperature, and an indicator light shows whether the heater is in heating mode or standby.

This small fish tank heater maintains water at a steady temperature, kicking on when it gets too cold and turning off when it reaches the desired temperature. Plus, with the memory function, you don't have to reset the temperature after power outages.

When using the hygger Mini Aquarium Submersible Heater, be sure to keep the heating rod fully submerged and use the two suction cups to install it vertically or horizontally on the tank wall. Always unplug the heater before water changes or cleaning, and allow it to cool down for at least 15 minutes. Stay safe and keep your aquarium at the perfect temperature with the hygger Mini Aquarium Submersible Heater!
