Aquarium Heater for 300 Gallon Fish Tank

The RISHORI Aquarium Heater boasts a dual temperature probe design, ensuring more accurate temperature control for your fish tank, with an error margin within ±1°F. It also features an auto cut-off function that shuts off power when the water level is low, providing overheating protection. This heater automatically cuts off power when the water temperature exceeds 34°C/94°F, safeguarding your aquatic inhabitants.

Offering the flexibility to switch between °F and °C, this heater caters to different temperature setting preferences. The dual digital display clearly shows the set temperature, real-time temperature, and heating indicator light, providing at-a-glance information.

Equipped with a three-pin plug, the heater helps prevent electric leakage and shock. Two strong suction cup brackets allow for stable placement in any corner of the fish tank.

Troubleshooting tips are provided for common issues. If the heater fails to heat up, it may be due to an incorrect temperature setting or an oversized tank, and the solution is to reset the temperature or choose a more suitable model. If the temperature is higher than the set value, it could be because a high-power model was selected for a small tank, and the remedy is to lower the temperature or opt for an appropriate power rating.

Precautions for use include fully submerging the heating rod under water to prevent burning and melting, placing the heater in an area with good water flow for even heating, and avoiding use in bottom filters where the water level may not be sufficient.

The RISHORI Aquarium Heater's titanium alloy heating element is shatterproof and corrosion-resistant, making it suitable for both freshwater and saltwater tanks. The impact-resistant sturdy cover makes it well-suited for large fish tanks and turtle enclosures.

The digital temperature control system offers a clear dual display of the set temperature and real-time power, along with a heating indicator. This 1200W heater is designed for tanks ranging from 150 to 300 gallons.

The heater's advanced safety features include automatic power cut-off when the water temperature exceeds 94°F or the minimum water level is not met. Error codes and an alarm alert users to high temperature (HH) or low temperature (LL) conditions, and the "AUTO shut off" indicator signals when the heater is out of the water.

The external controller allows for easy temperature adjustment without the need to remove the heater from the tank, with a temperature setting range of 59.0°F~93.0°F (15.0°C~34.0°C). The dual probe design ensures accurate temperature detection and precise automatic heating control, with an error margin within 1 degree.
