I have 1 250W and 1 200W Ebo Jagers Heaters In my 90 Gallon Tank. The Automatic Shutoff thing, I was just curious if it was normal for one of the heaters light to come on most of the time, while the other one rarely comes on. i keep the temperature dial at 78 on both, so when the heaters read 78 the light is suppose to turn off right? so im assuming that one of the heaters dont heat often because the other one is doing the job. correct me if im wrong? Either thats how it's suppose to be, or the other one that doesnt heat often is broken. I see the orange light turn on time to time, but it's rare.
