PULACO: Your Reliable Aquarium Companion

PULACO is committed to providing you with top-quality Aquarium services, making us the aquarium store you can trust. Our PULACO Aquarium Heater 50 Watt offers a seamless user experience with its external controller.

Using the external controller is a breeze. Plug it in, and the LED lights will illuminate. Press the button and continuously switch it until the LED display shows your desired temperature (ranging from 68°F to 93°F). Wait for 3 seconds, and the system will confirm the setting, and the heater will start heating up to your preset temperature.

The red light indicates the heater is in heating mode, and when it reaches the preset temperature, the blue light will turn on, and the heater will stop heating (it will restart heating when the temperature drops below the preset level).

For example, if the preset temperature is 68°F, and you want to adjust it to 78°F, simply press the button 10 times continuously. The LED display will show 78°F, and after 3 seconds of flashing, the setting is complete, and the heater will start heating from 68°F to 78°F.

Maintenance is hassle-free. This heater is a low-maintenance item, but for optimal performance and longevity, we suggest:

1. Regularly check the heater's working status and unplug it immediately if you notice any unusual signs.
2. Clean the heater's suction cups every 3 months using 140°F warm water.
3. If you find any soil or moss on the heater, unplug it, let it cool for a few minutes, and then clean it with fresh water, especially the heating part.

Cautions: - Use this heater only under the rated voltage conditions (110V-120V/60Hz). - This heater is designed for small freshwater or saltwater tanks and should not be used for chemical water or any other heating purposes, as it may damage the heater. - Children should use this heater under adult supervision. - The heater is non-detachable and IPX8 design, so do not attempt to disassemble it, as it will damage the device. - To ensure normal function and safety, the heater should be fully submerged. - Aquarium temperature can be affected by room temperature, which may cause a difference of ±3°F. - For optimal efficiency, use the heater in a circulating water tank, as still water can cause the heater's area to have a higher temperature than other parts of the tank.

The external controller features an LED temperature display and touch button, allowing you to easily and safely adjust the temperature.

The heating device is made of heat-resistant quartz glass, ensuring reliable performance.
