    Hi guys

    how deep must the coral sand be in the sump ?
    Would 10cm be deep enough or to deep ?


    Was thinking of having the skimmer in first compartment with overflow inlet, 2. then live rock , 3. then sand bed , 4. then live rock , 5. then pumps

    Would that be good enough?

    Kind regards

    why?
    Liverock is expensive. Rather use it in your display. Use all three chambers for DSB.

    You can seed the sand with half a cup from another reefers tank. You will get some coming from the main display but it will be limited compared to direct seeding. I agree with Riaan, LR in a sump does nothing long term. You can put it in there to seed the sand for a week.

    most will migrate. or you can place one LR on the sand for a month to let the creatures move down to the sand.

    So is everyone in agreement that the DSB should be 15cm, im sure iv read another thread that spoke about 18cm? Also, what is the max grain size for the DSB substrate?

    12cm?

    I read an overseas article - "after 12 cm increased benefits reduce exponentially"!

    it actually depends on the particle size. The super fine sand, yes then 12cm is ok. Playsand is aound 15cm. That is just the average used by everybody. Coarser and then you need deeper than 18cm.

    You can even use marbles. But then it needs to be something like 2m deep. (or more)

    So yes, there are a lot of different views. But if fine as in playsand, then 15cm is OK.

    Thanks for the input guys.. Everyone is talking about Reggies play sand.. Can someone please point me in the direction of a Reggies or another retailer(in gauteng) that stocks this playsand.. I need somewhere tried and tested, where the sand is free from silicate and other nasties..

    I got a big bag from Newlands Garden Center out in Pretoria East. R45 for a bag that I could not get out of my car boot. And I had to open it inside the boot and start scooping out of there. It is just as dirty.

    one or two hermit crabs.

    No need for you to clean it. Nut yes, sometimes pieces of cheato must be removed by hand.
