I recently bought a jebao dc-6000 for my 120 and it has crapped out after 2 months of use. i never even ran it on full power. I woke up and found the controller to be off but the power supply still lit. It has been an extremely disappointing experience. After the pump failed i lost my red sea regal, Borbonious anthias and my freidmani dottyback. that i have had for over 3 years. There has been no response from the company even after countless emails and phone calls. Do yourself a favor and buy a quality return pump.
