    ne1 here run a small pump in their overflow?

    I have seen reference to this, but haven't seen it setup. How does it work, and what size pump is good?


    Groceries or more reef supplies?
    What an easy decision...

    not to clear why you would want to do this? If you start sucking water out of your overflow then I can see it might start becoming an awfully noisy overflow[waterfall sound] because only so much water can flow in. Is this for a hang on the back overflow?

    I've heard of people running closed loops with the actual pump being located in the overflow, pumping into the aquarium... water level would remain the same, as it ends up going in the overflow anyways...

    I would think they're speaking of an external overflow and that the pump is a p/head used to draw out any air in the siphon u-tube assembly ...

    It's not junk, it's un-assembled DIY!
