The 200W aquarium heater by hygger is made of the most durable stable quartz, suitable for 20-55 gallon tanks and ideal for use in marine saltwater, freshwater, fish tanks, turtle tanks, betta tanks, and small ponds. The heater length is 11.2 inches, with a voltage of 110-120V/60HZ and a power of 200W. It comes with a US three-pin plug and a power cord measuring 6.0 feet + 4.0 feet. hygger offers a 12-month warranty on this product.

The heater features an intelligent constant temperature digital display controller that is easy to operate, allowing users to view the current water temperature and set the desired temperature by pressing the "+" or "-" button. The aquarium heater is designed with preventing dry burning, overtemperature alarm protection, memory, and intelligent constant temperature function, as well as Celsius/Fahrenheit conversion.

The temperature range of the heater is 59°F-93°F, with an accuracy of ±1°F. When the water temperature exceeds 95°F, the heater will automatically stop heating, and the LED will flash "HH" and emit a beeping sound. It will restart heating when the water temperature drops below 93°F. Additionally, if the heater is 5cm above the water level, it will shut off, the LED will flash "E1," and a beeping sound will be heard. The heater will resume heating when it is fully immersed in water.

The 200W fish tank heater is made of an ABS guard, with the heating element being explosion-proof quartz and the high-temperature-resistant nickel-chromium wire with silicon carbide thermal conductivity. This aquarium heater is stable, efficient, safe, and durable, with a longer service life and heating function. It is suitable for both freshwater and marine water environments.

The heater has a memory function, meaning that if the power is cut, it will maintain the temperature settings until the power is turned on again. When the current water temperature is 1°F/1°C below the set temperature, the light will flash, and the heater will start warming up. The hygger aquarium heater will always maintain the comfortable temperature for your beloved fish.

To ensure the optimal performance of the heater, it is recommended to completely immerse it in water and avoid burying it in sand or exposing it to air dry burning. When it is necessary to stop the heater, it is advised to disconnect the power socket and wait for 15 minutes before changing the water or removing the heater. Additionally, the external temperature controller must be kept away from the water, as it is not waterproof.

For best results, it is recommended to install the heater underwater near the water intake, either vertically or horizontally, with the vertical placement taking up less space. To further enhance the heat distribution, it is suggested to use a wave maker or circulating pump for the fish tank. Regularly cleaning and maintaining the heating plate is also crucial, as any impurities attached to it can reduce the heating efficiency.
