Hey everyone. I recently got my first tank and along with it I picked up a Jager heater by Eheim, but I am having an issue with it. I have it currently set at about 86 degrees (I am doing a fishless cycle) however I have a thermometer hanging in the water as well and it is currently reading about 78 degrees. The heater light rarely comes on, and when it does its not for very long. Is the heater dial somehow off and I have to calibrate it? I for some reason seem to remember reading somewhere that you might have to that with a new heater, although that seems a little ridiculous if you pay like 50 bucks for a heater it should work correctly out of the box. I was hesitant after reading a lot of mixed reviews about the Jager online, but decided to try it anyways. Looks like I made the wrong decision.
