Aquarium Submersible Heater for Fish Tank with Temperature Display and Control

The 【25W Small Submersible Heater】is suitable for 1-5 gallon fish tanks, with a Temperature Control Range of 59℉-93℉. When the temperature falls below the set value by 1℉, the heater will automatically heat up, and it will automatically stop heating once the set temperature is reached.

Featuring an 【External Controller and Built-in Thermometer】, this fish tank heater displays the water temperature of the fish tank in real-time via an HD display. The red light indicates the heater is actively heating, and the light turns off when the temperature is constant. Additionally, the display will show an error code if a heater fault occurs. However, it is important to note that the controller is not waterproof and should not be submerged in water.

【Easy To Use】, the heater allows you to set the desired temperature by pressing the button until you reach your preferred value. The display will flash the set temperature three times, then revert to showing the current water temperature, indicating that your setting is complete. You can also press the button continuously to cycle through the temperature range of 59-93℉.

Equipped with a 【Protects Dry Burn Control System, Safe And Reliable】, this heater adopts an advanced explosion-proof quartz heating tube, an anti-dry burning system, and over-temperature protection, ensuring enhanced safety. If the heater tube runs dry, the display will show "Er" and automatically stop heating. Similarly, if the water temperature exceeds 95℉, the controller will display "EE" and cease heating.

The【Small And Exquisite, High-quality Materials】design of this heater makes it ideal for small aquarium tanks. Crafted with premium materials and a scientific approach, the special plastic shell can effectively isolate a portion of the temperature, preventing fish from being scalded. This heater is suitable for both freshwater and saltwater aquariums, and it comes with a quality assurance for one year.
