Safe to use with protection mechanism
This fully submersible fish tank heater maintains proper temperature for your fish in a safety way, auto shut off when over-heats, resets when it cools down. The heater will shut off when removed from the water, and resume functioning upon return.
The heater heats up your aquarium at full speed once it plugged in. You can see Max on the screen. When it reaches the proper temp, it stops. Once the water temp drops 1 degree or so, the heater heats up again in low energy to keep the proper temp. You can see ECO on the screen. In this way, the heater saves energy greatly.
Shatterproof & Corrosion resistant
Corrosion resistant and shatterproof titanium tube construct heats fast, nearly unbreakable for both saltwater and freshwater aquariums. ABS plastic protective sleeve prevents fish from being scald.
