    I Have a 120 x 45 x 45 tank.

    I have 2 Sun-Sun 3000l/h pumps positioned at the 2 corners.

    After reading on the type of flow some guys have in their tanks, it seems that my tank could use more flow.

    I do not notice dead-spots.


    I was thinking of replacing the right hand side one with the double from Sun-Sun

    Should I?
    The left also has the outlet from my 1800 return pump for movement.

    On my 1.2 in the shop I use 2 x 6oooltr/hr sun suns and thats perfect so you could ether add the double one or add one 6oooltr/hr which will be best as 3 pumps at various positions is always better than two.

    mmmm .... With the return from your sump being so deep if there's a power failure does it not drain back into the sump too much? .... As for flow depends on what you going to keep .... Some corals prefer higher flow than others and then theres like some anemones that you might consider like in a year that MUST have great amounts of flow ....

    The return only drains up to the level, of the top of the outlet and not up to the level of the actual complete outlet. As soon as the top of the return sucks air, the return stops.
    I think it breaks the vacuum as the whole return is 35 mm. I did do the Eskom test, and my sump can handle all the return water.

    :thumbup: We mad marine members call it a siphon break :tt2:Great that you tested ... many a member here lands up in divorce court due to creating indoor swimming pools:lol:
    Sometimes nice to have different flows in a tank ... allows you to keep a variety of corals according to their flow requirements .... some guys recommend 60-100 times their water volume turnover in the display BUT take into consideration your scapeing is not that restrictive so thats a bonus ....

    Buy the 6000L .. It has a much broader flow. Personally Im also going to get a 6000 and maybe a 12000 because the single pumps are just to focused

    are those pumps controlable? if not id save up for a pump system that is controllable so that you get better random flow, makes a huge difference to ones flow patters. Good flow is far better than more flow as such
