Aqueon® Submersible Glass Heater 50 Watt 3.5 X 1.5 X 10.375 Inch

Aqueon's submersible aquarium heaters are ideal for both fresh and saltwater aquariums. These heaters are fully submersible and shatter-resistant. They come with an electronic thermostat that offers precise and dependable heating. You can adjust the heat settings from 68° to 88°. An LED lights up when the heater is working, and there's a built - in auto - shutoff to prevent overheating. The suction cups allow for fast and easy horizontal or vertical installation. Choose from five sizes to fit different aquarium sizes.

Using your Aqueon submersible glass heater is easy. First, make sure your aquarium is filled with water. Then, attach the heater to the side of the aquarium using the suction cups, either horizontally or vertically. Adjust the temperature setting to your desired level between 68° and 88°. The LED will light up when the heater is actively heating. Remember to keep the heater fully submerged in water at all times to avoid overheating. For maintenance, unplug the heater and gently clean it with a soft cloth every few months. If you notice any damage or if the heater isn't working properly, stop using it and contact customer support.
