[Rapid heat accumulation]: Aquarium heater using nickel-chromium heating wire, the heating speed is faster and the thermal conductivity is better. The heating rod comes with 4 strong, fixed and stable suction cups, safe and durable. [External controller]: The digital display screen shows the current temperature and the set temperature in real time, the temperature control accuracy is ±1 , and each press raises the temperature by one degree (20~34 ) [Multiple Use Modes]:Due to the strong suction cup, you can fix it inside the tank or put it at the bottom of the tank to use it (Note: Make sure to put it completely in water when you use it, and the bottom of the tank can’t be buried by sand and gravel!) [Safety]: Nickel-chromium alloy heating element, high efficiency and energy saving, with explosion-proof quartz tube ant, higher thermal conductivity, faster heating speed, longer service life and even heating, high quality plastic cover, effectively protect aquatic organisms from harm
