【200 Watts Aquarium Heater】: This 100W aquarium heater is ideal for 20 to 40-gallon saltwater or freshwater aquariums. It measures 8.3 inches in length, operates on 110-120V, and comes with a 6.6-foot power cord. Please refer to our size chart to choose the correct wattage for your aquarium.
【Overheating & Off-Water Protection】: The heater automatically shuts off and stops heating when the water temperature exceeds the preset level or if it becomes exposed to air. It will display an error code until the temperature drops below the preset limit or the heater is fully submerged again. Error codes: E1 – out of water; E2 – mechanical failure. This multi-layer protection ensures you never have to worry about "boiled fish"!
【Digital LED Controller】: Adjustable temperature range: 64℉-95℉, with an accuracy of ±1°F, you can easily adjust the temperature using the external controller without touching the water. The LED screen displays the current water temperature, preset temperature, and an auto shut-off warning. It's simple and user-friendly!
【Explosion-Proof Quartz Glass Aquarium Heater】: Made from explosion-proof quartz glass, this submersible heater utilizes high-temperature-resistant nickel-chromium heating wire and quartz sand for efficient heat conduction, providing rapid water heating and long-lasting performance.
