    when you say sandbed, do you mean your DSB or the sand in the display tank? For the sump, you can place a small power head in the sump to prevent a build up

    @Tremayn, agreed - but he did say in his sump.

    Well, you should not really have detritus settling out anywhere... try and adjust your flow across the surface of the sand bed so as to resuspend the detritus so that it can be skimmed out, further broken down etc. You could try and vacuum it very gently with a syphon so as not to disturb the sand itself, but that is a temporary fix.

    A DSB should not be disturbed if it is deep enough for its lower layers to be anoxic, providing a place for anaerobic bacteria to help with nitrate reduction. If it is disturbed then mixing occurs deeper in the sandbed, eliminating these anoxic regions and disturbing the associated microfauna etc.

    I think there are some snails that are good at eating that stuff as well. Can't remember what the name was.
    Nassarius Snail, but I think there's an issue with keeping them with hermits, and not sure if they will disrupt the dsb too much. Someone here will know.

    You can put a small powerhead in the sump to increase flow, as for the DSB, hemits as the thing. They move over the sand and keep the upper sand siphoned, but dont disrupt the DSB, all you need to do is feed them.

    If you have settlement on the sand, it means that your flow is not enough most likely.

    What size return pump do you have. And what is the width of your sump.

    What you should aim for is that the water going over the last divider be between 6 to 10mm between glass top and actual water level.

    sorry for all the confusion guys, next time i'll be more specific. I meant the sandbed in my dt. I think i need to increase the flow in the dt. My dt holds 30l, my only flow is the return from a hailea 6520 in the sump. My sump is just a 1ft tank that holds my heater, return pump, bag of seachem seagel and some floss that i thought would help.

    No skimmer?

    Anyway, the flow in your display is not able to keep the rubbish in suspension until it goes over the overflow.
    Adding another small powerhead will work.

    Anyway a tank of 30L only, how do you do your auto top up. A 10mm water level drop surely will affect your salinity.

    my ato is a gravity fed ato. Nope, no skimmer. The plan was not to feed or feed very little, i have no fish. Lots of goggas in the water column though.
