Aqueon Preset Heater
Compact in size and requiring no manual adjusting, the new Aqueon Preset Heaters take the guess work out of keeping tropical aquariums at the correct temperature. Each heater is preset to 78 degrees Fahrenheit with an automatic safety shut-off to avoid overheating and damage. They are made from shatter resistant materials, are fully submersible and have an LED indicator light to show when the heater is actively heating. The Aqueon Preset Heaters are available in 4 sizes and are suitable for 5 gallon through 75 gallon aquariums.
