Description
Easy to Hide, Compact & Space-Saving – Measuring just 5.04″ x 1.4″ x 1.02″, this 50W aquarium heater features a slim, compact design that takes up minimal space. Ideal as a mini aquarium heater for 5–10 gallon nano, betta and turtle tanks, the black housing blends easily into the aquarium for a clean, discreet look.
Beep Alarm & Smart Safety Protection – The nano aquarium heater automatically shuts off when the water level is too low, helping prevent dry running and overheating. A flashing “EE” error code with a beep alarm provides a timely warning when the water temperature reaches or exceeds 97°F (36°C), while a flashing “Er” error code with a beep alarm alerts you when the water level is too low.
Convenient Digital Temperature Display – Easily monitor the current water temperature and check your set temperature with the clear LED display. The external controller and indicator light make this small fish tank heater easy to monitor, adjust, and control at a glance.
Adjustable Temperature & Memory Function – Easily set your desired temperature from 59–93°F in 1°F increments with the external temperature controller, keeping your hands dry while adjusting this submersible aquarium heater. The memory function retains your last setting after a power interruption, so you don’t need to reset the temperature.
Safe & Durable Design – Built with an explosion-proof quartz heating tube and fire-resistant ABS housing, this fish tank heater provides reliable heating, added protection, and lasting durability for everyday aquarium use.
Important Safety Tips – Fully submerge the aquarium heater before powering on and place it in an area with good water circulation. Always unplug the heater and allow it to cool for 15 minutes before water changes or cleaning.
