Information about AQQA Safe, Durable & Smart Aquarium Heating
This aquarium heater offers superior safety, durability, and intelligent temperature control to keep your aquatic pets comfortable all year round.
Built for Safety and Longevity
Crafted from heat-resistant quartz glass and a robust PC plastic cover, this heater boasts a double-sealed design, making it explosion-proof, shatterproof, and IP68 waterproof. It’s built to last and provides a much safer environment for both you and your fish, ensuring your pets won’t fear the cold winter.
Intelligent Automatic Heating with External Control
Experience hassle-free temperature maintenance with the intelligent automatic constant temperature function. It comes with an external temperature controller for easy adjustments, offering a temperature range of 59°F-93°F (15°C-34°C). You can easily switch between Celsius and Fahrenheit by holding down the button at the top of the controller for 5 seconds. The heater will automatically restart heating if the water temperature drops by just 1℉ (1°C) from your set temperature. Plus, it remembers your temperature settings even after a power outage.
Clear Digital LED Display
The controller features a digital LED display that shows both the current and set temperatures. A constant red light indicates the heater is actively working. Once the water reaches 93℉ (34℃), the heater will stop, and a constant blue light will illuminate. If the heater is exposed to air or not fully submerged, a blue light and “E1” fault code will appear, signaling a safety shut-off.
Simple and Versatile Installation
Installation is quick and easy. This submersible fish tank heater can be placed either vertically or horizontally using the included adjustable hanging rack and two suction cups. For optimal performance, always ensure the heater is completely submerged in water before turning it on and install it near a water flow area to ensure even heating.
Broad Application and Important Precautions
This heater is suitable for both freshwater and saltwater aquariums. For your safety and the heater’s longevity, always cut off the power and allow the heater to cool for 10 minutes before cleaning your aquarium or performing a water change.

Efficient Heating & Energy Saving



















I was looking for a slim heater to have on the narrow end of a tank or potentially across the bottom, and this one looked like it would fit the bill. It heats up my 55gal very quickly, with water circulating via a separate filter/pump.
The common internet wisdom is to use several small heaters instead of one large heater, because if one of the temperature sensors goes bad you’ll have more time to find out before your fish get cooked. Since this one is a bit oversized for my 55 gallon tank, I’m going to try and find a power strip that can be turned off via a seperate temperature sensor, as a backup.
Keeps my aquatic turtles warm for those cold winter months
Great size, heats up really fast and perfectly for the animals. It reads really great and stays accurate to the right temperate. Very to install and use.
Set up a new 60g and this thing brought the water from 66¡ãF to 78¡ãF in about 15 minutes. The controls were so intuitive and clear that I didn’t even need to look at the instructions and the guard casing helps put my mind at ease while also making it feel extra durable for using with my delicate flowerhorn. The price is up there compared to some heaters but you definitely get what you pay for and you’re paying for quality. It hasn’t been up long but so far I am exceedingly happy with it’s functionality.
