The Aqueon Pro 300 Submersible Aquarium Fish Tank Heater is engineered to provide precise, consistent water temperature regulation for large aquatic environments. Designed for both freshwater and saltwater tanks up to 100 gallons, this heavy-duty 300-watt heating unit features an advanced electronic thermostat accurate to plus or minus 1 degree Fahrenheit.
