About this item
Product details
Aqueon Submersible Aquarium Heaters are made from thermal shatter-resistant quartz glass and designed to absorb impacts, making them extremely durable. An electronic thermostat stops heating once set temperature is reached. A power indicator light turns on when the unit is heating and is equipped with a 6-foot power cord. UL approved, the heater is also programmed to turn itself off when not properly submersed to avoid overheating and damage. This heater can be positioned at a vertical or horizontal angle and used in freshwater and saltwater aquariums. Wattage heaters are available in 50W, 100W, 150W, 200W and 300W.

Good looking heater, I like that it has a lifetime warranty. I don't know if it is keeping the right temperature since I don't have a thermometer to check.

Happy for my fish.
Probably a bit more than needed for my 30 gal. tank but I went through a number of smaller ones, different brand, that disappointed. My fish are much more active and the water temp is staying right on.

Purchased mine 14 months ago. Has no problem heating my 120 gallon tank by itself. I keep my tank at 82 degrees and never fluctuates or struggles.
