Find out if it's the 36V version. It should say somewhere on the pump or the controller input.
I think it is 36VDC at 150W or less. Then go to amazon or ebay and get one.

That looks in the ballpark. I think these pumps are also supposed to have built in intelligence (or the controller does) so if the power supply isn't sufficient - it won't run.
Given the massive inflation by the reef vendors, I'd give this a try personally.. but it's your pump.
