Information about AQQA Versatile and Safe Quartz Aquarium Heater

This multi-functional quartz aquarium heater offers adaptable placement, precise temperature control, and essential safety features to keep your aquatic environment stable and secure.

Flexible Dual-Purpose Design

This heater provides dual-purpose functionality for your convenience. You can use it with the included protective shell and two strong suction cups to prevent accidental burns, ensuring safety for your fish and curious hands. Alternatively, the single quartz tube body with its own suction cup allows for a more compact setup, reducing space inside your tank.

Intuitive External Controller with Dual Display

The external controller with its dual digital display makes monitoring your tank’s temperature simple. It simultaneously shows both the real-time water temperature and your set temperature. Easily adjust the temperature within a range of 59℉-94℉ (15℃-34℃). For added flexibility, you can convert between Fahrenheit and Celsius by long-pressing the button for 8 seconds.

Advanced Safety Protections

Safety is paramount with this heater’s built-in protections. If the heater is more than 1.5 inches out of the water, it automatically powers off, and the digital controller displays the error code “E1”. The heater will automatically resume normal operation once fully submerged. Furthermore, it features high-temperature automatic power outage: if the water temperature exceeds 95℉ (35℃), heating stops immediately, and the controller displays the error code “HH”. The temperature display returns to normal once the water temperature drops below 94℉.

Important Usage Notes:

• For the most accurate water temperature detection, please use this heater in conjunction with a water circulation product.
• We recommend regularly disassembling and cleaning the heater tube every 1-2 weeks to ensure optimal performance.
• Always allow the heater to cool for 15 minutes in the water before removing it from the tank to prevent damage.
