Are you looking for a reliable way to maintain the perfect temperature in your fish tank? Look no further than the AQQA Aquarium Submersible Heater! Designed specifically for 10-21 gallon fish tanks, this 150W small submersible heater is the perfect solution. With a temperature control range of 59℉-93℉, you can easily set your desired temperature and let the heater do the rest.

One of the standout features of this heater is its external controller and built-in thermometer. The built-in thermometer allows you to keep a close eye on the water temperature in real-time with the HD LED display. The controller is not waterproof, so be sure to keep it out of the water. When the temperature is below the set value, the heater will automatically heat up, and it will stop heating once the desired temperature is reached.

Setting up and using this heater is a breeze. Simply press the button until you reach your desired temperature, and the display will flash the value three times before returning to the current water temperature. You can also easily cycle through the temperature range of 59-93℉ by pressing the button persistently.

When it comes to safety, the AQQA Aquarium Submersible Heater has you covered. It features an advanced explosion-proof quartz heating tube and an anti-dry burning system. This double protection ensures that your fish tank remains safe at all times. If the heater tube runs dry, the display will show "Er" and automatically stop heating. Additionally, if the water temperature exceeds 95℉, the controller will display "EE" and again, stop heating.

Not only is this heater functional, but it's also aesthetically pleasing. Its small and exquisite design is perfect for small aquarium tanks. Made with high-quality materials and a scientifically designed plastic shell, the AQQA Aquarium Submersible Heater effectively isolates part of the temperature to prevent scalding fish.
