What to Compare Before Buying
- Tank volume: This model is specified for 76-151 L tanks. Check your aquarium size before choosing it.
- Temperature control: The heater adjusts in 0.5°C steps between 15°C and 34°C. Compare that range with the temperature you want to maintain.
- Controller placement: The external controller is not waterproof, so it needs to stay outside the aquarium.
- Heating style: It uses automatic constant temperature heating, which is relevant if you want a heater that maintains a set point rather than a simple on/off design.
Setup and Correct Use
The heater is submersible and needs to be fully in water before use. Use the external controller to set the temperature, then allow the heater to maintain the selected setting automatically.
Always unplug the power before cleaning the tank or changing water. If the display flashes EE, the temperature has gone above 36°C. If it flashes Er, the heater is not fully in water.
Before You Decide
Check that your tank is within the stated 76-151 L range, and confirm that the external controller layout suits your setup. Make sure you are happy with the 15°C to 34°C temperature range and the requirement for the heater to stay fully submerged during use.
