SAFETY & DURABILITY

Made from heat-resistant quartz glass and a PC plastic cover, this heater features a double-sealed design, ensuring explosion-proof and shatterproof performance. The IP68 waterproof rating guarantees safety and reliability, making it ideal for both human and pet use. Your beloved fish and pets will no longer fear the cold winter months.

INTELLIGENT AUTOMATIC HEATING

The digital LED display on the front of the controller shows the current and set temperatures. A constant red light indicates proper operation, while a constant blue light signifies that the desired temperature has been reached (93°F/34°C). Additionally, if the heater is exposed to air or not fully submerged, the blue light will illuminate along with an E1 fault message.
