HITOP 15W Mini Aquarium Heater: Adjustable Heater for 1-4 Gallon Fish Tanks, with External Controller, for Betta Fish Bowls

The HITOP 15W/25W/35W Aquarium Heater is a finger-sized, compact heater that is easily hidden in fish tanks. This heater is suitable for use in fish tanks under 8 gallons. The 15W model is recommended for 1-4 gallon tanks, the 25W model for 2-6 gallon tanks, and the 35W model for 4-10 gallon tanks.

To use the HITOP Super Mini Heater, fully submerge it in water and power it on. Turn the temperature regulator knob to the desired setting, with each dot representing 2°F. The upper red light indicates that the heater is heating. Attach the included thermometer sticker to the outside of the tank to monitor the water temperature, as this can be influenced by factors such as water volume, circulation, and the thermometer's position.

The heater's key specifications include a length of 3.7in/9.5cm, a diameter of 0.47in/1.2cm, a 1.5M/4.9ft power cable, and a power rating of 15W, 25W, or 35W. It operates on 110-120V/60Hz and has a temperature range of 64-93°F/18-34°C.

The accessories included are a thermometer sticker, 2 suction cups, and a bottom protective cover. The heater is recommended for use in small tanks, such as those for fish, turtles, and bettas, as its low power output helps prevent overheating and provides a comfortable living environment.

The HITOP Aquarium Super Mini Heater is designed to be discreet, with a slim, finger-like profile that can be placed in the corner of the tank without affecting its aesthetic appeal. It is made of thickened quartz glass and quartz sand, making it anti-explosion, corrosion-resistant, and able to distribute heat evenly.

The external temperature controller allows users to adjust the temperature by turning the knob, with the set temperature displayed by the green light. The red light indicates when the heater is actively heating. The heater also has a power-off temperature memory function, so the temperature setting is automatically restored after a power outage.

The heater's sturdy and durable construction, with a double-seal design, helps prevent water leakage and ingress, ensuring a safe and reliable operation in both freshwater and saltwater tanks. The package includes the heater, power cable, thermometer sticker, suction cups, and a bottom cover, as well as a 12-month warranty.
