    I have a tank which is 48 x 36 x 46, so how deep should my sand bed be and how much should I put in the sump?

    Your DSB should at least be 150mm deep in your sump. Usually for a DSB to be effective the surface area should be at least 80% of your display. If not then you can look at adding macro algea (like Cheato) in your sump or ORCALABS Bio Cubes (which alot of guys are having success with). As for your display a thin layer of sand (+/-30mm) will do or even no sand (all depending on what you want to keep).

    Your sump is too small to house an effective DSB. It can get confusing trying to decide what filtration you need. Sand bed in tank is generally only for aesthetics, so make it as deep/shallow as you want
    Best thing is to draw up a list of what fish/coral you want and design the filtration system based on their needs.

    I definitly want sand in the DT. Do I need sand at all in my sump? I just want a few corals, some fish and critters.

    I thought so about the sump. Okay. I will set up a plan for the coral, critters and fish that I want eventually and then repost on here.

    You dont need sand in the sump. Rather keep filtration as simple as possible.

    A good place to get ideas is to look through the member setup section and get an idea of what can be done and what works.

    Hi,

    I have a question, I have got place in my sump for a DSB. i only filled the tank on Sunday.

    i now need to get the sump. running with filter materials and rocks etc.

    My question is, can you use the coarser sea sand you find on some of the beaches in the DSB and can you put Bioballs etc in the same compartment above the DSB.

    thanks

    yes you can. Would be better if you can "suspend" them on piece of eggcrate above the sand, with a 5 to 10mm space between sand surface and eggcrate.

    the depth is not as important as the size and shape of the sand you are planning to use , the idea is too create a space that does not allow for oxygen to move through , the smaller the grain size the quicker this happens ....ok wait this will take all day to explain , i'll look for Calfo's write up on dsb's and try post a link
