The Aqueon Preset Heater line helps keep heating simple by keeping your aquarium at just the right temperature, all the time. Coming from the factory preset at 78 degrees — a perfect temperature for most tropical aquariums — there is no need to adjust it or worry if your setting is too hot or too cold.
Plus the compact design makes these heaters a great choice for most aquariums and skill levels. They are fully submersible and are durable and shatter proof. A small red LED indicates when its actively heating. There is also an automatic safety shut-off to protect against overheating.
The Aqueon Preset Heater line comes in 50W, 100W, 150W and 200W sizes and have an MSRP anywhere from $15.99 to $30.99, but if you look around, you’ll probably be able to find it at a better price.
