I purchased a used Jebao Dc12000 to increase the flow in my 120 to abate Triggerfish aggression. I was running it on the 4th setting because my overflow couldn't keep up with any higher. I bought a bigger overflow and today ran the pump full speed. Keep in mind the pump was making noise on the 5th setting despite being cleaned. Well only an hour or so of running it on high it completely quit. The power supply was very hot and I am letting it all cool down unplugged. I did take it apart and clean it prior to this. I was used but really clean when I got it just two weeks ago. I don't know if it will restart. I have a Jebao on my 90 but it was new when I got and no trouble. Any tips?
