I have my 40 breeder set up to flow in a counterclockwise direction. I have my intake and spraybar on the left side. This is the way that was shown how to set it up in an Eheim filter manual. It is not because of the Coriolis Effect.

I've added a small Rio 50 powerhead to the right side. Its feet are on its backside. It is placed on the right side pane blowing toward the left side. It flows about 60 gph or thereabouts. It is actually enough to cause the water to flow in a counterclockwise direction all by itself. This surprised me! With it turned off, I still get a counterclockwise flow from the intake and spraybar.

Thank you for the link. I'll be glad to read it.
