Thanks all. The pump that failed is still making a louder noise than the other. As I said it was my back up. Since I need new back ups anyway, I am thinking I may just pick up a couple of new MJ1200s and start fresh with the move.
I would recommend Sicce Syncra Silent pumps - good solid brand and they have barbed output connectors for the tubing - I used these in my JBJ 65g tanks (in the reef I used one Sycra 1.5 + a Mighty Jet Midsize DC pump)
