    Good Day PLL,

    I was thinking of building a new sump, running all reactors, skimmer and return pump externally, however, I want to make use of a close loop system to make sure there is no ditrus building up and a way to skim the return chamber for that nasty oil build up on the water...

    Any ideas or input will be appreciated :thumbup:

    Closed loop does not work with an open sump. Closed loop means that from the intake, to the pump and back to the tank is sealed off. No open water. Pump is hard plumbed. Best is to use ballvalves on the intake and outlet sides so that you can remove the pump for maintenance.

    Closed loops are nice. But they do have their drawbacks. The pumps used take more wattage for the same flow. Depending on your layout, its a lot more difficult to change the output direction. Each corner/elbow adds more back pressure to the pump. Pipework and ballvalves can add extra a lot of money to your layout.

    But, no pumps in the tank. Depending on your intake, it can be anemone safe.

    Do you want to pull water out from one side of the sump, pumping it to the other side?

    @RiaanP, I want to create internal flow in the sump so that no ditrus will settle... instead of using power heads or flow pumps...

    If you have cheato in your sump, take note that small pieces do break off. And its easier to remove them from a powerhead than from a hard plumbed pump. Especially the old style powerhead with strainer fitted to the intake. Also powerheads use less watttage than return style pumps. At the end, its still your choice.

    i like the idea, a suggestion, when housing all your equipment external, its nice to put them in a glass container, even a shallow one , for those accidents that happen.

    now with a cls in your sump, you can get away with a cheap hailea 6530 or so and get massive flow as on a level plane and cls the loss of power is not much.
