Why You’ll Love It
The hygger aquarium quartz heater features 3 intelligent functions and an intelligent automatic power-off system, providing overheating/low temperature warnings and out-of-water warnings for saltwater and freshwater tanks of 40–280 gallons.

Key Features
Advanced Heating System
The hygger 115 Aquarium Heater Quartz is crafted with safety and efficiency in mind. It utilizes explosion-proof quartz glass and high-temperature resistant nickel-chromium heating elements. It heats tank water rapidly, maintaining a stable temperature within a ±1°F accuracy. Its double-layer explosion-proof design offers enhanced reliability and safety for your aquarium.

Intuitive Digital LED Display Controller
The external temperature controller features a clear digital LED display showing the set and current water temperatures, current power usage, and error codes. With a simple press of the set button, you can easily adjust the target temperature between 59-93°F (15-34°C).
The controller’s LED indicators clearly indicate the operational status: a red light indicates the actively heating, while a white light signals the water has reached the set temperature.

Enhanced Safety Features
The hygger Aquarium Heater is equipped with 3 intelligent safety features designed to protect both the heater and its circuitry from damage:
1. Dry-Run Protection: It will display a flashing “auto shut off” message and cease heating if it is not fully submerged.
2. Overheating Protection: Display “HH” and stop heating automatically if the water temperature exceeds 95°F, ensuring the safety of the aquarium inhabitants.
3. Low-Temperature Alert: Flash “LL” and emit an alarm if the temperature drops below 58°F, indicating a potential issue that requires attention.

Convenience and Ease of Use
The memory function retains the last temperature setting automatically after power outages. It is particularly convenient when unplugging for water changes or maintenance. The heater includes suction cups and a mounting bracket for easy installation. To achieve more accurate temperature control, it is recommended to position the heater at a 30-45° angle and use it with a water circulation system.

I have had many 1000+ watt heaters and find Hygger’s to be easy to set up right out of the box. Setting the temperature is intuitive and the digital display is quite nice, it literally shows the watts being used while the heater is on. The outer case makes it so my animals (sting rays) will not burn themselves, even if laying directly on it. I will be switching over to these 1000 and 1200 watt heaters.
This heater works great for my 50 gallon corner aquarium. I live im new England and the tank is a long am outside wall and the tank temp are steady. I had a small problem that was not repairable and the company sent a replacement free of charge. They stand behind their products. Highly recommend.
This is a compact, workhorse of a water heater that has kept my fishies alive and very happy. The cold front jumped up on us and I wasn’t quite prepared without this and I thought all my warm-water fish were going to die. Thankfully they were just a little shell-shocked and when I got this heater in there, they have been very active and loving it.
