Hello, I'm going to be getting a Cade 900 s2 soon (YAY!!!) and am trying to plan my equipment purchases. I'd like to get a return pump, and know there are several things you have to consider first, but have no idea what the specifications are that I need to be looking at as far as the Cade 900 goes. Do any of you have return pumps that you love? I'm hoping to get two - one primary pump, and a cheaper one to keep as a back up in case something goes wrong. I was thinking of getting a Jebao as the cheaper backup pump, but would I need to consider what my primary pump will be and whether or not the two pumps are easily interchangeable? Thanks for any help!
