    Hi,
    with some posts about water movement, water circulation, dsb contact time etc. i came up with the following idea, what you think?

    Instead of the normal:
    overflow - skimmer - dsb - return
    type of sump why not have the overflow go directly into the return chamber with a big return pump so you have lots of water going through your DT.
    Then you have a small 300l/h pump also from the return chamber pumping water to the skimmer chamber, so you have small flow through the skimmer and dsb back into the return chamber but big flow through the DT - return chamber.

    If I got this right? Its the same as having a small flow down to your sump, through your filter system and back up again, with strong power heads in your DT giving a good water movement. Don't see the difference?

    But I might be wrong?

    if i can use a big return to get a lot of water moving through the DT then i can remove my pumps in the DT for a neater look.

    So you want to use your overflow as a "Closed Loop" entry point.
    Can work, why not, but if you want a closed loop, get a proper closed loop.

    Big return pumps uses more wattage W than smaller powerheads that delivers the same amount of flow. And loosing out on delivery due to head height.

    But a closed loop do not loose out due to head height.

    I agree with RiaanP, rather do a proper closed loop system!
    And yes, your tank will look a lot better with all the pumps removed and not so maintenance intensive as power heads usually are!
