hygger 100W Mini Submersible Digital Display Aquarium Heater for Small Fish Tank, Compact and Fast Heating Thermostat…

With its small size and quick heating capabilities, the Hygger 100W Mini Submersible Digital Display Aquarium Heater is ideal for small fish tanks. This oval-shaped heater is useful for keeping the temperature in your aquarium at the correct level. It comes in 50W for 1-6.5 gallons and 100W for 6.5-13 gallons.

Measuring 2.7×1.4x 4.5 inches, this heater comes with a 5-foot power cord, making it suitable for indoor use. Equipped with two strong suction cups on the back, installation on glass, acrylic, or plastic tanks is effortless.

The external controller allows easy temperature adjustment, displaying the temperature in Fahrenheit. You can set the temperature range from 63℉ to 94℉ with an accuracy of 1℉. Simply press the button repeatedly until you reach your desired temperature, then wait for the digit to flash three times to confirm the setting. Keep the controller dry, as it is not waterproof.

Featuring a digital display on the front, an indicator light turns red when the heater is heating and off when heating is complete. The built-in thermometer continuously displays the water temperature, showing the set temperature digit only when you press the controller.

Reliable thermostat functionality ensures that the tank water remains at the set temperature. The heater stops heating when the water temperature reaches the set value and resumes heating when the temperature deviates by 1℉. In case the water temperature exceeds 95℉, the heater automatically shuts off, displaying HH on the LED, and resumes normal operation when the temperature drops below 95℉.

This fully submersible aquarium heater is suitable for both freshwater and saltwater tanks. If the top part of the heater is out of water, it will automatically shut off, displaying E1 on the LED, and return to normal operation once fully submerged again.
