Eheim Jäger 300W

The Eheim Jäger 300W is the flagship wattage in the Jäger line, purpose-built for large aquariums of up to 400L requiring substantial and consistent heat output. The TruTemp recalibration system ensures the thermostat remains accurate over extended periods of use, reducing the need for replacement. Shatterproof borosilicate glass construction delivers durability for both freshwater and marine environments. A built-in safety shutoff protects the heater and livestock by cutting power whenever the unit is exposed to air. Fully submersible at any angle, it integrates seamlessly into sumps, display tanks, and large species setups.
