Review on HITOP 300 600W Aquarium Heater: LED Display, External Controller, Adjustable, Accurate for Aquarium up to 200 Gallon by Maria Skim

aquarium heater arrived quickly (3 days after click). It is as described. It has a small digital display. I set the heater to 78F and it heated the reef tank from 73F to 79F in a short amount of time. Even though it's set to 78F, it shows the tank temperature as 79.5F. However, I think it was a good idea to replace my old 18" glass bottom heater (which never kept my tank at a stable temperature). When active heating is not required, the wattage of the heater drops to zero. I recommend it and will buy it again. if I ever install another tank (ps: 600w max power is overkill for my 70g reef tank).
