Special Features
Fast & Stable Heating for Large Tanks: 300W heater quickly warms 40–70 gallon freshwater or saltwater aquariums, maintaining a stable 59–93°F range to support tropical fish health.
Explosion-Proof & Fish-Safe Design: Dual quartz glasses and a protective ABS cover prevent cracking and direct contact, reducing burn risk and ensuring safe, long-term use.
Multiple Safety Protections for Peace of Mind: Automatically stops heating at the set temperature, shuts off with alarm above 97.7°F, cuts power when out of water, and activates APS protection within 10 seconds if a fault is detected.
Smart Controller & Energy Saving: Digital LED controller displays real-time temperature with 0.5°F precision. Automatically reduces power near the target temperature to avoid overheating and help lower energy consumption.
Easy Installation for Aquariums: Secure suction cups hold the heater firmly against the tank wall. Install near water flow and avoid dead corners. Velcro allows the controller to be mounted outside the tank. Fully submersible for aquarium use only.
