Description

This 300W aquarium heater is suitable for freshwater and saltwater aquariums ranging from 115 to 300L. Using our aquarium heater, you can create a comfortable and safe living environment for your beloved fish.

• Durable Material: Our aquarium heater uses quartz as the heat transfer medium, enabling rapid, uniform, and efficient heat transfer, resulting in greater energy savings. Its heat-resistant ABS shell and controller ensure reliable performance, safe operation, and long-lasting durability.
• Safety Protection System: Built-in anti-dry-burning and overheat protection functions ensure the safety of your aquarium. The heater automatically stops heating when the water temperature exceeds the set temperature and automatically starts heating when the water temperature falls below the set temperature, maintaining a stable and comfortable environment for your fish.
• Power-Off Design: When the heater is removed from the water, fault code E1 flashes, and heating stops. The temperature setting is automatically memorized after the water level returns to normal, eliminating the need for resetting. Convenient and safe. This inverter aquarium heater can save you a significant amount on your electricity bill annually. Economical and environmentally friendly.
• Dual LED Digital Display: Equipped with dual digital display windows, you can clearly view both the water temperature and the set temperature simultaneously, even in the dark. Easy to observe temperature changes and enhanced safety. Our heater uses an external thermostat, allowing you to adjust the temperature without removing the aquarium.
• Installation Tips: This 300W aquarium heater is suitable for freshwater and low-salinity aquariums ranging from 115 to 300 liters. Ensure the heater is completely submerged in water before connecting it to the power source, and install it near a water flow to prevent uneven heating.
