Pawfly Submersible Heater for Betta Fish Tanks (Up to 10 Gallons)

Fully Submerged Heater: Perfect for Fresh, Marine, and Tropical Aquariums

Fully Immersed Design

The heater should be completely submerged in water during use to ensure optimal performance and safety. It is suitable for fresh, marine, and tropical aquariums up to 10 gallons. Place it where there is good water circulation to ensure even temperature distribution. Avoid burying it under sand or gravel to prevent overheating and damage.

Adjustable Temperature Control

Enjoy precise temperature regulation with a wide range of 59 °F to 94 °F (15-34 °C). The device offers slight deviations of ±2 °F. Simply press the "+" or "-" button on the controller to set your desired water temperature easily.

Timely Temperature Detection

The built-in thermostat ensures that the heater activates when the water temperature drops below your set point, indicated by a red light. Once the desired temperature is reached, the heater automatically stops and the indicator light turns green. This timely temperature detection helps maintain stable and healthy tank conditions.

Overheating Protection

In case of overheating, the heater will automatically shut off to prevent excessive water temperatures. This feature helps protect your aquatic pets and keeps them healthy by maintaining safe water conditions.

Shatterproof and Safe Construction

The heater is made from 2 mm extra-thick quartz glass, which not only prevents electric leakage but also provides shatterproof durability. The heavy-duty isolation cover ensures that your fish are safe, as it always keeps them out of contact with the heating element. This design eliminates the risk of scalding fish, offering a safer and more reliable aquarium heating solution.
