Almost all of my Jabeo equipment died within 6 months or so of buying it. All of the wavemakers and circulation pumps died. One of my 2 main pumps died a couple years ago after less than a year and I simply put back in place my trusty 10 year old Eheim. The lone exception was the main pump in my main tank. I think it is a DC-6000. It went along for close to 4 years but now is showing signs of dying. It can't seem to keep the same speed and is surging. This is causing all sorts of havoc with the auto-fill and siphons. So I will end this chapter in cheap Chinese pumps and move back to the old reliable Eheim pumps.
