hygger Aquarium Heater 100W (16-26 gal) | External Display, Overheat & Leakage Protection

Discover precise, durable heating for your tanks

The hygger 100W submersible aquarium heater is designed to support both freshwater and saltwater setups from 16 to 26 gallons. Built with a TA2 titanium alloy outer shell and a protective Teflon coating, it resists corrosion and scaling while delivering steady warmth. A quartz glass tube encases a nickel-chromium heating wire, promoting rapid, even heat distribution for reliable temperature control. The shell-less design simplifies cleaning, and the exterior remains smooth to the touch, even after days of operation.

Managing water temperature is straightforward thanks to the external digital controller. It features a clear three-digit display that shows both the target temperature and the real-time water temperature, with quick-switching between Fahrenheit and Celsius. A red indicator lights during heating, while a green indicator shows when the water has reached the set temperature. This setup helps you monitor conditions at a glance and adjust as needed, without guesswork.
