Dreyoo 2 Set 300W Aquarium Heater for 40-55 Gallon Tanks

The high-quality heating wires and 2 mm thickened corrosion-resistant quartz glass make this product suitable for both freshwater and saltwater aquariums. With the included suction cups, the heaters can be easily and securely fixed in the fish tank, without any complicated installation steps, providing a convenient and quick setup. The red indicator lights on both sides will turn on when the heater is powered, allowing you to easily monitor the working state.

The clear screen and suction cup design allow for easy temperature observation, with the added convenience of °F/°C switchability. To turn off the heater, simply long press the "PWR" button. It is important to choose the right heater power and quantity based on the actual tank capacity and desired temperature.

The heating speed depends on the size of the fish tank, but installing the heater close to the circulation pump or filter can help distribute the heat more evenly, allowing the entire tank to warm up quickly.

The 300W Aquarium Heater is suitable for 40 to 55-gallon aquariums. The heater is 11.8 inches in length and operates on a 110-120V, 5-foot plug cable. The package includes 2 fish tank heaters, 2 aquarium thermometers, and several suction cups.

The adjustable temperature range of the aquarium submersible heater is 68 to 93 °F, allowing for precise control of the water climate within a 1-degree difference. The sensitive and reliable thermostat ensures a uniform temperature, with the red light indicating when the heater is actively warming the water and automatically shutting off when the desired temperature is reached.

The package also includes 2 Aquarium Thermometers, with an immersion probe and suction cup that can be easily placed in the water, enabling you to closely monitor the tank's temperature.

The distinct design of the aquarium water heater utilizes 2 mm thickened quartz glass, making it suitable for both freshwater and saltwater aquariums. The compact and hidden design makes it easy to integrate into the tank, while also being durable and safe for both people and water animals.

It is important to note that the fish aquarium heater should be adjusted to the desired temperature first, then the suction cup should be fixed, and the heater must be completely submerged in the water before powering it on. Additionally, if you need to clean the tank water heater, you should wait for it to cool down before removing it.
