The first I had stopped working after a month.
I have the temperature set at 76 and my tank is at 71 because another heater is in there which isn't powerful enough to raise the temperature past that.
Am I doing something wrong? I simply turned the dial and plugged it in. I see that the heater light is turning on but it's not raising the overall tank temperature.
