Are you tired of worrying about the water temperature in your aquarium? The AQQA Submersible Aquarium Heater is here to put your mind at ease. Designed with your fish's safety in mind, our heater is made of explosion-proof quartz glass material and a high-temperature resistant nickel-chromium heating wire with silicon carbide heat conduction. This ensures faster water heating and a long-lasting performance that you can rely on. With just 2 hours of heating, the temperature increases by 1℃, providing optimal conditions for your aquatic friends.

But that's not all - our aquarium heater features an external temperature controller with an LED digital display, allowing you to easily monitor the current water temperature and adjust it to your desired setting. The controller is equipped with an indicator light that flickers when heating and remains steady when the temperature is constant. The shell of the heater is made of a high-temperature resistant PC material, protecting your fish from potential scalding and ensuring their safety at all times.

Worried about power outages? Don't be! Our AQQA Submersible Aquarium Heater comes with a memory function, so even if the power shuts off, it will remember your temperature settings and resume heating once power is restored. Additionally, the heater has dry burning-resistant protection. When the heating rod is 5cm above the water surface, it automatically powers off and displays "E1" on the controller. Once submerged again, it returns to normal operation without any manual intervention required.

Installation is a breeze with the adjustable hooks on the back of the controller. Simply hang it on your fish tank without the need for any tools. The hook size can be adjusted to fit the thickness of your tank, ensuring a secure and reliable attachment. Plus, our AQQA products are backed by a 1-year warranty, so you can purchase with confidence knowing that we stand behind the quality of our products.
