Hygger Aquarium Heater with Digital Controller for Saltwater and Freshwater Fish Tanks

The product description highlights several key features and safety considerations for the 100-Watt Aquarium Heater by hygger. Firstly, the heater is designed with over-temperature protection - when the water temperature exceeds 95°F, the heater will automatically stop heating, the LED will flash "HH," and a beeping sound will be emitted. The heater will resume heating once the water temperature drops below 93°F.

The heater also incorporates low-temperature protection, starting the heating process when the current water temperature is 1°F/1°C below the set temperature. This ensures the tank maintains the desired temperature for the well-being of the aquatic inhabitants.

Several important usage tips are provided. It is crucial to fully submerge the heater in water, avoiding any exposure to air, which could lead to dry burning. When it is necessary to stop the heater's operation, the power source should be disconnected, and a 15-minute wait time should be observed before changing the water or removing the heater.

The external temperature controller must be kept away from the water, as it is not waterproof. For optimal performance, the heater is recommended to be installed underwater near the water intake, either vertically or horizontally, with the vertical placement being more space-efficient.

The use of a wave maker or circulating pump is advised to ensure even heat distribution throughout the aquarium. Regular cleaning and maintenance of the heating plate are necessary, as any impurities attached to it can reduce the heating efficiency.

The 100-Watt Aquarium Heater by hygger is made of durable, stable quartz, suitable for use in 15 to 40-gallon aquariums, including marine saltwater, freshwater, fish tanks, turtle tanks, betta tanks, and small ponds. It features a length of 11.2 inches, a voltage of 110-120V/60Hz, and a power rating of 100 Watts. The power cord is 6.0 feet long, with an additional 4.0 feet of length.

The heater is equipped with an intelligent, constant-temperature digital display controller that is easy to operate. Users can press the "+" or "-" buttons to set the desired temperature, which is displayed on the screen. The heater incorporates features such as preventing dry burning, overtemperature alarm protection, memory function, and Celsius/Fahrenheit conversion.

Additionally, the heater is designed with overheating and leaving water alarm protection. If the water temperature exceeds 95°F, the heater will automatically stop heating, the LED will flash "HH," and a beeping sound will be emitted. The heater will restart heating when the water temperature drops below 93°F. If the heater is raised 5 cm above the water level, it will shut off, the LED will flash "E1," and a beeping sound will be heard. The heater will resume operation once it is fully submerged in water.

The aquarium heater is made with ABS guard, explosion-proof quartz heating elements, and high-temperature-resistant nickel-chromium wire with silicon carbide thermal conductivity, ensuring stability, efficiency, safety, and durability. It also features a memory function, maintaining the temperature settings even after a power outage. The hygger Aquarium Heater is suitable for both freshwater and marine water environments, providing a comfortable temperature for your beloved fish.
