    The Mag 7 has a 1/2" intake/outflow and the Mag 9.5/12 have 3/4". On the otherhand, all of the Quiet One pumps have 1" connectors.

    As a newbie in pluimbing, I'd be interested in comments about whether this difference is meaningful and if it depends on the application (e.g. skimmer vw closed loop?

    Depends on your skimmer I know a mag 5 fits on my skimmer with no extra plumbing.........and if your using a return what size pvc will you be using this will also make choosing a pump easier. But if I were buying a pump I would buy one bigger then I needed and use a valve to turn it back some day you will want a change in tank size or more flow and you will already have it. I know that a 1 1/4 inch bulkhead has alot less flow then a 1 1/2 inch one so yes a small size difference could mean a difference in flow rates.

    Most of the mag pump flow ratings are done with 1" tubing, regardless of the intake/outflow size.

    I would go with the MAG pump. I have a 9.5 here on my return and it has to date worked flawlessly and is plenty quiet enough. IMO they offer good value.

    I have the same as OSD. I actually have mine hooked up to my new SCWD (thanks to tang_man) and it is putting out great flow still.
