Safety Features: Experience peace of mind with our aquarium heater's advanced safety mechanisms. The internal explosion-proof and insulated quartz heating tube, coupled with a special ABS material exterior, ensures no melting at high temperatures. The nickel-chromium heating wire offers stable and rapid heating efficiency. A dual safety protection chip automatically shuts down the heater and flashes a code if water levels are low, dry burning occurs, or the water temperature exceeds 95℉, safeguarding your aquatic friends.
Versatile for Freshwater and Saltwater Tanks: Perfectly suited for tropical fish like Betta, Guppy, Tetra, Corydoras, Arowana, and other freshwater and saltwater species needing warmth in winter. Ideal for fish tanks, aquariums, and small fish ponds where aquatic organisms thrive.

Power-Off Memory Function: Enjoy your vacations without worry. The heater's memory function restores previous settings after a power outage. The controller displays real-time water temperature with an indicator light—red when heating and green when the desired temperature is reached—providing a visual of its working status.
Convenient Control Experience: Featuring a simple external controller that's easy to operate without wet hands in winter, eliminating safety hazards. Adjust the temperature effortlessly between 59°F/15℃ to 93°F/34℃ in 1-degree increments.
