The Heater is factory calibrated at a controlled room temperature of 21 °C. Variables such as lower room temperature, wide temperature fluctuations, lack of an aquarium cover, presence of submersible pumps and filters, aquarium placement in proximity to heat or cooling sources, may require a higher wattage for proper control. To ensure accurate temperature, verify setting with a reliable thermometer.
It’s a submersible heater with:
- On and Off Pilot Light Indicator
- High Impact safety glass
- For Fresh or Saltwater aquariums
