Aqueon Preset Aquarium Heater

Aqueon Preset Aquarium Heaters are a hassle - free solution for your aquarium! Pre - set at a calibrated 78°, which is ideal for most tropical fish, these heaters need no adjustment. Made from shatter - resistant quartz glass, they're built to last. The automatic safety shut - off feature ensures the heater won't overheat. An LED indicator lights up red when it's actively warming the water. It's accurate to +/- 1°. Remember, room temperature changes might cause minor differences in the actual water temperature.

Using this Aqueon preset aquarium heater is easy. First, make sure it's fully submerged in the aquarium water. You don't need to adjust the temperature as it's already set at 78°. Just plug it in, and when the LED turns red, it's heating the water. For safety, don't operate the heater outside of water. If you notice the LED isn't working or the water isn't reaching the right temperature, check the power connection. To keep it in good condition, clean the heater regularly with a soft cloth. Avoid using abrasive materials as they can damage the shatter - resistant quartz glass. Also, keep in mind that room temperature variations can slightly affect the water temperature.
