    Im planning a compact version of the external venturi reactor for a 20Long. The reactor will probably be no bigger than 12". I have a few questions.

    1) Will this powerhead work? http://www.marinedepot.com/Eheim_1212_Aquaball_Powerhead_Adjustable_Flow_Aquarium_Powerheads-Eheim-EH1212-FIPHAD-vi.html
    It has an air integrator, is this the same as a venturi? I assume it is. Does it have enough flow for a 20L?

    2) What about the outflow tube, what goes on that? As I understand it, water is pushed through the reactor using the powerhead, and then exists out the other end, but what does one use to disperse the flow?

    Thanks :)

    I'd use a Rio 180 pump myself, they are small and easy, cheap etc.
    Reactor tube only needs to be maybe 8"x2".
    Add a few bioballs
