Information about AQQA Smart Aquarium Heater
This aquarium heater provides precise temperature control and robust safety features, ensuring a stable and secure environment for your aquatic pets.
Adjustable Temperature with Easy Conversion
You can easily set the temperature within a range of 59℉-93℉ (15℃-34℃). Each press of the button increases the temperature by 1℉/1℃, and the settings conveniently loop from the highest back to the lowest. To switch between Fahrenheit and Celsius, simply press and hold the button for 5 seconds.
Dry Burning-Resistant Protection
Safety is key. If the heating rod is more than 2.4 inches out of the water, it automatically powers off and displays an “E0” error code. It will automatically resume operation once fully re-immersed. To extend its lifespan, always ensure the heater is in the water before powering it on, and let it cool in the water before removing it.
Leakage Protection and Overtemperature Alarm
This heater includes an electricity leakage protector and overtemperature protection. If the heating rod detects the water temperature is 3℉/3℃ higher than your set temperature, the current water temperature display will flash as a high-temperature alarm, and heating will stop. It automatically returns to normal once the water temperature drops to your set point.
Fast Heating with Intelligent Control
Benefit from fast heating and an intelligent controller. The heater begins warming when the water temperature is 1℉/1℃ below your set temperature and stops once the set temperature is reached. A red light indicates heating, a green light means the set temperature has been achieved, and the light disappears when an error code occurs.
Important Usage Precautions:
Over time, scale can build up on the heating rod, affecting heat dissipation and potentially leading to safety issues. Therefore, we recommend regularly disassembling the heating rod shell to clean the rod body.
Exquisite Workmanship

ABS Protective Casing
High quality protective shell, efficient heat dissipation while preventing burns

Nickel Heating Wire
High purity nickel complex heating wire, efficient heating, fast heating

Thickened Quartz Glass Tube
Thickened explosion-proof quartz glass tube for safer use

Strong Suction Cup
The powerful suction cup can adsorb to any corner of the fish tank, and if it loses suction, it can be cleaned




























Great product, works as advertised.
Made well and keeps set temperature in my 220-gallon tank consistent.
The product is terrific. My only complaint is that one must choose a temperature setting in one whole degree implements ¡ª-for example 78.0 degrees F or 79.0 degree F. One cannot choose 0.5 degree settings. However the actual water temperature display is in 1/10 degree values¡for example, actual water temperature display can be 78.3, 78.4, etc.
Easy to use and to set temperature, and also seems to work well even when placed in a near-horizontal position within my shallow sump. I give the product 4 out of 5 stars.
Al d¨ªa de hoy llevo 8 d¨ªas utiliz¨¢ndolo y funciona perfectamente, espero que no falle a futuro como varios comentarios que estoy leyendo aqu¨ª, ojal¨¢ no estalle, es lo ¨²nico malo que viene en vidrio y se puede fracturar.
