I am looking into getting an overflow to drain into my sump from my 56 column and dont really know what flow rate I should shoot for.
i really like the ones from this site http://www.drsfostersmith.com/produ...=AA&srccode=cii_5784816&cpncode=23-32270776-2
the options are 300, 800, or 900 gph
thanks
