Aquarium Heater for Fish Tanks

Before using the product, please ensure that the power supply voltage matches the rated voltage. For all glass heaters, carefully inspect for any damaged parts prior to installation. Do not use the heater if the cord is damaged or cracked, and contact the manufacturer in such cases. The heater is designed with an IPX8 rating, and it is non-detachable, so do not attempt to disassemble it, as it will damage the device.

It is essential to fully submerge the heater under water before plugging it in. After unplugging the heater, wait at least 10 minutes before changing the water or removing it from the water. It is strictly forbidden to remove the heater immediately after unplugging. Burying the heater under sand is also not recommended.

To ensure even and thorough heat distribution in the aquarium, it is recommended to place the heater in an area with good water circulation. The aquarium temperature may fluctuate depending on the ambient room temperature, and it is normal to have differences within ± 3°F. If the room temperature is below 60°F, a more powerful heater than the recommended one should be chosen.

To avoid injury, do not touch the heating part directly. The 300W aquarium heater is suitable for fish tanks ranging from 40 to 75 gallons. The heater length is 11.5 inches, and the power cord is 6 feet long, with a voltage of 110V/60Hz.

The heater features an easy-to-access dial on the top, allowing for convenient adjustment of the water temperature from 65°F to 89°F. The red light automatically turns off when the target temperature is reached, and the heater then maintains a constant temperature in your marine or freshwater aquarium.

The package includes a 300W small aquarium heater, 2 suction cups, and a thermometer strip. Always keep the heater fully submerged under water before plugging it in, and unplug it and wait for at least 10 minutes before performing any aquarium maintenance or removing it from the water.
