    2speed pump?

    I have one.....funny thing is I can't hear the difference between the 2 speeds. I guess the only way to tell is up is high n push switch down for low.

    What's better....run on high for 6 hrs or on low for 12 hrs.?

    You can tell the difference by the pressure reading on your filter gauge or put your hand in front of the return.

    I run mine on low for six hours and water is crystal.

    Forgot to mention I use high when adding bleach to mix good and when I need better skimming.

    So I probably run pump for 8 hrs.

    +1 for running at low speed. Filtration is likely to be better. You can run it on low and you may be able to run it for less time than you think. Follow the suggestions in this article: Determine Pump Run Time

    When it comes time to replace my single-speed pump motor (which I may do before it wears out), about the only time I would run it on high speed is immediately after adding chemicals and when I am vacuuming with the Polaris.

    The only strange thing from your post is that I would expect to hear a noticeable reduction in noise when running at low speed vs. high speed.

    You would think you would hear the difference or that's one quiet pump.

    You know....I may have to go back and see how I wired it. Is it possible I wired it for single speed?

    It is definitely worth taking another look at if there is a shadow of a doubt.

    I put a 2speed on my WhisperFlo. The difference is dramatic. On low, I have to touch it to tell if it's running. On high, I can definitely hear it as soon as I get around the barrier fence. I'd recheck your wiring.
