Adjustable Submersible Aquarium Heater for Marine and Freshwater Fish Tanks

DOMICA 100W/200W/300W Aquarium Heater This aquarium heater is designed to provide a comfortable and safe environment for your beloved fish. With its advanced features and user-friendly design, it ensures optimal water temperature regulation for a thriving aquatic ecosystem.

Product Highlights: - Voltage: 110V-120V/60Hz, with a US standard plug suitable for the US, Canada, and Mexico. - Heating Accuracy: ±3°F, ensuring precise temperature control. - Intermittent Heating Design: Heater will heat for 5 minutes and stop for 2 minutes (indicated by the light turning off) to maintain accurate water temperature and provide a comfortable heating environment for the fish.

Temperature Adjustment and Installation: 1. Turn the blue button on the top of the heater to adjust the temperature as needed. The yellow number displayed in the round circle indicates the set temperature. 2. Securely place the heater upright in the water, ensuring the suction cup adheres fully to the tank's side for complete submersion. 3. Plug in the heater, and it will take a few hours (depending on tank size and ambient temperature) to heat the water to the set temperature. Be patient during this process. 4. When turning off the heater, unplug it before removing it from the water to avoid dry heating, which can damage the device. 5. Unplug the heater 10 minutes before water changes to prevent disruption.

Maintenance and Safety: - Regularly check the heater's working status. If you notice any unusual signs, unplug it immediately. - Clean the heater's suction cups every 3 months using warm water (140°F) and soak them for a while. - If you find any soil or moss on the heater, unplug it, and clean the heating part with fresh water after 10 minutes. - Do not use any other liquids to clean the heater, as they may damage the device. - Ensure the heater is fully submerged in the water during operation. Install it near water flow or use a suitable water pump to aid heat diffusion. - Do not put your hands in the water while the heater is operating to avoid electric shock or burns. - Unplug the heater when cleaning or maintaining the aquarium. - Do not expose the heater above the water, as it can cause the glass and other parts to break.
