At-a-Glance Temperature Display The heater rod shows real-time water temperature, with an indicator light that changes color to indicate heating status. Red when heating, green when the desired temperature is reached, providing immediate feedback.

External Knob Controller & Memory Function An external knob controller allows you to quickly set the temperature without getting your hands wet, especially during frigid winter months. The adjustable wide temperature range is 59°F to 93°F, in 1-degree increments, ensuring precise control. Settings are remembered when unplugged, making temperature adjustments effortless during water changes.

Out of Water Shut Off Protection Equipped with out-of-water shut off protection, this heater ensures it does not overheat and cause harm to your livestock. It automatically turns off before reaching the desired temperature, safeguarding your aquatic pets.

Shatterproof Plastic Guard A shatterproof plastic guard protects fish and turtles from impacts and makes it easy to detach for cleaning.

Ideal for Small Fish Tanks The slim, flat profile of the mini tank heater measures 4.3'' x 1.8'' x 0.9'', making it space-saving and easy to hide behind filter, wood, or rock. The two strong suction cups allow easy mounting. The flat design lets you place it either vertically or horizontally at the gravel-free aquarium bottom, heating up low water level turtle tanks effectively.
