Hygger 200W Submersible Aquarium Heater with Digital Controller

The hygger 200W aquarium heater is designed for use in 20 to 55 gallon fish tanks, suitable for both marine saltwater and freshwater environments, as well as turtle tanks, betta tanks, and small ponds. Crafted with the most durable stable quartz, this heater is 11.2 inches in length and operates on a 110-120V/60Hz power supply with a 6.0-foot power cord plus a 4.0-foot plug.

The heater is equipped with an intelligent constant temperature digital display controller that is easy to operate. Users can simply press the "+" or "-" button to set their desired water temperature. The controller features an accuracy of ±1°F and a temperature range of 59°F to 93°F. The heater also includes a memory function, allowing it to maintain the temperature settings even after a power outage.

For added safety and efficiency, the hygger aquarium heater is designed with several protective features. The over-temperature protection mechanism will automatically stop the heating process when the water temperature exceeds 95°F, causing the LED to flash "HH" and emit a beeping sound. The heater will resume heating once the water temperature drops below 93°F. Additionally, the heater is equipped with a low-temperature protection feature, triggering the heater to start warming the water when the current temperature is 1°F/1°C below the set temperature.

To ensure optimal performance and safety, it is crucial to follow the provided warm tips. First, the heater must be completely submerged in water, avoiding any exposure to air or burying in sand, which could lead to dry burning. When it is necessary to stop the heater, users should disconnect the power socket and wait 15 minutes 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 best results, the hygger aquarium heater should be installed underwater near the water intake, either vertically or horizontally, with the vertical placement taking up less space. The use of a wave maker or circulating pump is recommended to ensure even heat distribution throughout the fish tank. Regular cleaning and maintenance of the heating plate are also essential, as any impurities attached to the plate can reduce the heating efficiency.

With its high-quality construction, advanced safety features, and easy-to-use temperature controls, the hygger 200W aquarium heater offers a reliable and efficient solution for maintaining the ideal water temperature for your beloved fish. The heater comes with a 12-month warranty, providing peace of mind and assurance for aquarium enthusiasts.
