About This

• Rapid & Stable Aquarium Heating: 800W submersible aquarium heater provides stable heating for 80–200 gallon freshwater or saltwater tanks. Adjustable temperature range 59–93°F (15–34°C), ideal for creating a healthy environment for tropical fish and aquatic life.
• Explosion-Proof Quartz Glass: Built with 2PC quartz glasses, nickel-chromium heating wire and silicon carbide heat conductor for rapid heat conduction. The high-temperature resistant ABS protective shell prevents fish from burns and ensures long-lasting, safe performance.
• Intelligent Safety Protection: (1) Auto shut-off heating when set temperature is reached; (2) Overheat protection with power-off and alarm above 97.7°F; (3) Out-of-water protection to prevent dry burning; (4) APS system cuts off power within 10 seconds if malfunction detected.
• Smart Controller & Energy Saving: Digital LED controller shows real-time °F temperature and adjusts in 0.5°F steps. Auto frequency control cuts power to 10–30% near the target temperature for stable, energy-saving heating. Red/green indicator shows heating status; light off means heating stops.
• Easy Installation: Strong suction cups secure the heater to the tank wall. Avoid placing it in dead corners to prevent fish from getting stuck. Velcro lets you mount the controller outside the tank. Fully submersible design works for aquariums, fish tanks, and small ponds.
