Hygger 600W Aquarium Heater for Freshwater & Saltwater with Over-Temperature Protection

Product Overview

This aquarium heater is designed with two critical safety features: an automatic power-off mechanism and an audible alarm system.

Overheating Protection

The built-in dual temperature probes effectively monitor the water temperature. If the temperature exceeds 94°F (34°C), the heating element automatically halts operation to prevent the risk of cooking your fish. Simultaneously, the controller displays the error code "HH" and flashes "Hi," alerting you to the issue, ensuring the wellbeing of your aquatic pets.

Low Temperature Protection

Conversely, when the temperature falls below 59°F (15°C), the heater automatically activates to restore warmth. In this scenario, the controller emits an audible alarm and shows the error code "LL," flashing "Low" until the water temperature rises above the specified threshold, thus ensuring your fish remain comfortable.

Anti-Dry Operation Function

In cases where water is insufficient, the temperature sensor calls for an immediate stop in heating to prevent dry burning. The controller will sound an alarm, display an error code "L1," and flash "Auto Off" to warn you of the situation, safeguarding against potential fire hazards.

Important Usage Note

Before changing the water, ensure you unplug the heater and allow it to cool down adequately. This precaution will prevent burns from residual heat or damage to the shell.

Compatibility and Specifications

This heater is versatile, suitable for both freshwater and saltwater environments. The wattage applications and respective tank capacities are as follows:

• 400W heater: Suitable for tanks of 40-80 gallons, with a control range of 59-90°F.
• 600W heater: Designed for 66-135 gallons, also operating within the 59-90°F range.
• 800W heater: Works with 80-220 gallons, maintaining the same temperature control range.
• 1000W heater: Fits tanks of 130-260 gallons and retains the 59-90°F control spectrum.

Safety Assurance

This heater features a dual temperature sensing system, preventing overheating and undercooling. The audible alarm and automatic shut-off add an extra layer of safety to keep your aquatic friends secure.

After-Sales Service

We offer a comprehensive one-year after-sales service, ensuring your queries will be addressed promptly.

Selecting the Appropriate Wattage

To choose the right wattage, calculate using the formula: (Fish Tank Length × Height × Width) + 1000 × 2, which will guide you to the required heater wattage.

Advanced External Digital Controller

Equipped with a high-definition external LCD display, the digital controller shows current water temperature, set temperature, and heating status. This design enhances waterproofing and allows for easy temperature adjustments without needing to wet your hands. It features a temperature adjustment range between 59°F and 93°F with an accuracy of ±0.1°F.

Intelligent Safety Features

Your safety is paramount—this aquarium heater will issue warnings via the sensing system. Codes displayed on the external controller include Overheating (HH), Low Temperature (LL), and Dry Burning (L1). Thanks to an intelligent chip, the heater stops when temperatures exceed 93°F and resumes heating when they drop below 59°F.

Efficient Heating and Memory Function

Using stable nichrome heating wire and a thickened quartz glass explosion-proof tube, the hygger heater guarantees rapid and even heat exchange, efficiently reaching the desired temperature while minimizing energy costs. Plus, thanks to its memory function, this fish tank heater retains settings during power outages and resumes automatically once electricity is restored.

For added convenience, this adjustable aquarium heater comes with three suction cups, a controller bracket, and a hook, along with a 10ft external power cord for easy installation. The 600W adjustable aquarium heater is perfect not only for home fish tanks but also for fish markets, aquariums, and fish ponds, accommodating a range of aquatic environments.
