    well i decided to upgrade my 4ft (250lt) tank to a 5ft (672lt)
    so i collected the tank and i am now doing a fresh water test for about 3 day to see if there are any leaks.

    full system
    670lt 1400 x 640 x 750 DT
    250lt sump (dsb)
    8 x t5 55w globes
    TS2 skimmer
    600 x 700 ATS

    i am planning to have no wave makers in the tank and i am going to do a closed cercuit return with 2 x 4000lt pumps.

    the overflow will be a skinny overflow the complete right side of the tank 20mm wide


    the DT with Fresh water in

    Ok so this is how i want to do the plumbing for this upgrade, what would your views be on this.

    the DT is a 5ft the CZ is a butcher box, Refugium will be a 3ft tank and the sump will be a 4ft tank

    By running the return from the cz and refugium back to the skimmer, wont you skim out all the copepods they add?

    Are both the 4000ltr pumps retunring water to the tank or is one of them on a closed loop system?

    Why not have a separate pump after the DSB feeding the cz and refugium.

    both 4000ltr pumps on a closed loop system, i could run a pump to feed the CZ and the refugium after the DSB, but where would the return from the Refugium be 1.skimmer chamber 2.over DSB 3.in return chamber

    Id go with this one.
    What do you plan on keeping? 8000lt/hr doesnt seem like enough flow.

    Personally id go with this route.Let your skimmer be your first line of filtration. Then DSB and then the rest.

    By the looks of the drawing, the return pumps arent closed loop and all the water they pump on will leave the tank via the overflow??
    if this is the case, youll get 8000lt/hr flowing through your sump. That sort of flow rate over a DSB will render it useless.

    closed loop is when the overflow is connected directly to the inlet of the pump and then water is fed straight back into the tank.
    You can still have closed loop, but youll need one pump to run circulation to the sump/dt then more pumps running on a closed loop.
