    I have repaired the leaks on the plumbing now. I was generously given this 2800 pump to use but I may need a regulator if the water is flowing too fast.

    How do I know if I need this regulator? My tank is 46 x 38 x 42.

    i am assuming the pump is 2800l per hour? I have used 100x system volume with no problems. Its only an issue if the sand is blowing around

    Nooooo, its only an issue when the water splashes iver the sides onto your carpet or laminated floor...

    Seriously though: if ditected properly, that pump should not be too much. Instead of throttling it, try and spread its flow around

    How can one spread it's flow around? More pipe inside the DT?

    I'm not sure if it would move the sand around because I want the pump flow to be more controlled before I put the live rock and the sea water in. At least if I have a regulator I can slow it down if the sand moves around.

    I put an elbow in on mine so it doesn't blow directly on the sand but creates abit of flow around the tank

    Yeah I think mine is too small for the strong flow.

    So I had a look at your tank and that uplift pump might be too strong unless add a pipe to your outlet and make a spray bar but even so it could cause too flow. It will depend on what you plan keeping in there.

    Once you add liverock most turbulent flow will be gone. The 2800l/h return is definately not to much.

    Are you meaning return pump or flow pump?

    @Clowning Thank you. I haven't decided what I want to keep in there but for a tank my size I want it to be a little more tranquil that what I saw last night. Does the return flow limit the type of fish and coral I can keep?

    @JakkieSteenkamp What about the sand though. How does the presence of the live rock reduce the effects of the strong flow on the sand and the fish and critters eventually in there? The tank is quite small considering? Do u mean rocks in the sump?

    2800ltr/hr isnt strong flow at all. Youll still need to add flow pumps to the tank.
    Return flow doesnt effect what livestock you keep, but may effect the fitration you have, eg DSB is more influenced by flow than other methods.

    So the majority are saying I don't need a regulator? Should I launch the tank with the sea sand, sea water and live rock without a regulator then?

    The flow pumps are those submerged fans on the side of the tanks?

    The point is not to have any dead spots in your tank where detritus can build up. So rather than having the flow concentrated in one direction disperse it thus decreasing the strength of flow in one direction. As suggested earlier with a spray bar. Worked for me...

    Leave off the regulator. You can always split the return line into two if you feel its giving too much directional flow.

    Correct, flow pumps are thoise fan looking things stuck on the inside.

    Okay I like the idea but how will this limit the kind of things I want to keep in there. You said it depends what I want to keep in there. Is it a big limitation?
