    @SantaMonica how about the flowrate for drop scrubbers. There is a small inlet at the bottom and only air bubbles drive the flow and for circulation there is no outlet. What If I use small pump to force the water inside an open outlets on the side? Just curious? Because I thinkdrop wouldnt do an as good of ajob compared to waterfall type of scrubbers

    DROP's get more than enough circulation. If below the waterline, water exits the top. If below the waterline, water circles back down and goes out the big hole in the middle of the bottom.

    Water circulation is just not that important. Air/water interface turbulence is. And the bubbles provide this. Waterfalls have less air/water interface turbulence that our upflows do.

    Therefore, a water pump will not help at all.
