50W Aquarium Heater – This 50W heater is suitable for 5-10 gallon tanks, measuring only 5.3 inches in length. Its compact size saves space and is easy to hide in aquariums, making it an ideal choice for small fish tanks, betta tanks, and turtle habitats
Reliable & Durable – The submersible fish tank heater features explosion-proof and corrosion-resistant thickened quartz glass, paired with a high-temperature-resistant ABS casing for enhanced sturdiness and extended lifespan
Safety Design – Equipped with overheat protection and dry-run cutoff, the heater automatically stops working when water temperature exceeds 97°F or out of water, effectively eliminating hazards and safeguarding aquatic life
Adjustable Temperature – The external controller allows temperature adjustment in 1°F increments, with a range of 64-93°F. The built-in digital display shows real-time temperature and working status. It also features a memory function, retaining the last setting after power restoration without manual reset
Fast Heating & Precise Control – This heater features high-quality nickel-chromium heating wires for rapid and even heat distribution. The smart temperature sensing system continuously calibrates water temperature, maintaining a deviation within ±0.5℉. When the temperature drops below the set value, the heater activates automatically. Upon reaching the desired temperature, it switches to low-power mode to stabilize heat with minimal energy consumption, protecting aquatic life from temperature fluctuations
