Description

Need reliable temperature control for a freshwater aquarium up to 80 Gal (300 L)? This fully electronic aquarium heater is designed to keep water temperature steady around the set point, helping to prevent large, unsafe fluctuations that can stress fish. It is aimed at freshwater setups where consistent heating and simple monitoring are priorities.

The heater uses advanced electronic control to deliver accurate, stable heating and provides 24/7 monitoring to maintain the chosen temperature. A 360 degree indicator light ring gives an immediate visual status from any angle – red while heating and blue when the desired temperature is reached – so you can check at a glance, day or night. The unit cuts power automatically if it is removed from water, and a Heater Guard reduces the risk of breakage during routine maintenance. A large grip dial lets you set temperatures between 72 and 90 degrees Fahrenheit (22 to 32 degrees Celsius), a range that covers most tropical freshwater requirements. Its fully submersible design allows horizontal or vertical placement to suit flow patterns and tank layout.

Key Features

  • Advanced electronic temperature control – provides consistent, accurate heating for a more stable aquarium environment
  • 24/7 monitoring with automatic power cut when out of water – reduces risk during maintenance or pump failure
  • 360 degree indicator light ring – instant visual feedback, red when heating and blue when at temperature
  • Wide adjustable range with large grip dial – easy setting between 22 and 32 degrees Celsius to match typical tropical freshwater needs
  • Fully submersible and can be mounted vertically or horizontally – flexible placement to improve heat distribution
