About this item
- 300-Watt Aquarium Heater - The 300-watt aquarium heater is suitable for saltwater and freshwater aquariums from 150 to 300L. The heater length is 27 cm, the voltage is 230V, and the power cord is 3 meters. Please choose the appropriate power aquarium heater according to our size chart
- Overheating and water outflow protection - When the water temperature exceeds 34℃ or falls below the minimum water level, the heater will automatically cut off the power and stop heating, it will display an error code and sound an alarm until the water temperature is below 34℃ or the heater is completely immersed in water. Error code: high temperature; LL low temperature; automatic water shutoff. Multiple protections to help you get rid of "boiled fish"!
- Digital LED controller - temperature adjustable range: 15-34℃, accuracy: ±1℃. You can use the included bracket to mount the controller on the edge of the tank to adjust the temperature without having to reach into the water. The LED controller displays current water temperature, preset temperature, operating power, and more warning signs for low/high temperature/auto shut-off. The operation is very simple!
- Efficient explosion-proof - the aquarium heater is made of explosion-proof quartz glass and high-temperature-resistant nickel-chromium heating wire. This heats water faster, safer and longer. The heater guard is made of high quality PC plastic to protect your fish from burns
- FULL ACCESSORIES AND WARRANTY - This aquarium heater comes with the accessories you need. Package includes 1 aquarium heater, 1 controller, 3 suction cups, 1 stand and 1 hook

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
