Available in four wattages—100W, 200W, 300W and 500W—you can choose the right size to match the scale of your tank, from a cozy 10 gallons up to more expansive enclosures. Its compact form and quiet operation make it a discreet companion for your aquatic habitat.\u003c\/p\u003e\n  \u003ch3\u003ePrecision you can feel\u003c\/h3\u003e\n  \u003cp\u003eAt the heart of this heater is intelligent frequency conversion that keeps water temperature within a tight range. With 1℉ precision, the device automatically stops heating when the water climbs 1℉ above your target and wakes up again when it falls 1℉ below. The result is a steadier environment with less daily adjustment, whether you’re keeping tropical fish, dwarf species, or turtles.\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003e1℉ temperature stability helps maintain a reliable environment for your aquatic pets\u003c\/li\u003e\n    \u003cli\u003eAutomatic shutoff and reactivation prevent overshoot and undershoot\u003c\/li\u003e\n    \u003cli\u003eDual temperature display mode supports Celsius or Fahrenheit for easy setup\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003ch3\u003eVersatility and performance\u003c\/h3\u003e\n  \u003cp\u003eThis submersible heater is designed for versatility.

A high-temperature protection feature stops heating if the limit is exceeded by 1 degree, and a waterless power-off function prevents operation when the heater is lifted about 5 cm above the water surface.
