    Hi All

    I just have a few questions regarding my substrate.

    I have recieved a bunch of decent sand from the ocean. It was collected below the water line at low tide.

    I would just like to know what would be the easiest way to clean and bleach the sand? Also do i need to sift the sand and remove the smaller particles and then remove the larger particles? the sand is really fine.

    Also is this the correct way of doing things. Or should i rather just go buy some quality aragonite.

    Is the sand still live, ie. has it been kept submerged and oxygenated? If so, it can be used. It must not be so fine that flow inside your tank will kick it up. Remember that there will be a certain amount of die off, which will cause a nitrogen cycle to occur, depending on the maturity of your tank. I don't understand why you want to bleach the sand. Anyway, it's not possible.

    If the sand is dead, ie. dried, then rather buy some reggies playsand. I believe that a lot of people up-country are useing it successfully.

    I see you are in Johburg, the chances that you would have die off is big rather go the Reggies sand or Aragonite way.

    You could, but it would not have much benefit for the reason that you've pointed out. The change in temerature would probably kill every living thing in the sand. I'd rather use dead, dry sand and rinse it well and start by seeding it from a fellow reefers dsb.

    Thats exactly the answer i needed. I'm rather just going to use aragonite! Much easier!

    Any recommendations to brands and type?

    Hi Johan - yes - Look at my tank's thread.... I ONLY used sand from Bloubergstrand.

    I have never had any issues with the sand, Johan. Not in the 4 years that I have had it.

    I never use expensive aquarium products lol, so can't comment on aragonite. The important thing to watch out for is that its grain size is that of sugar. Slightly finer is also good, but not coarser. The grain size determines what type of organisms are going to thrive in the dsb.

    I just agitate the top +-1 to 1.5 cm of my tank's sand bed (I have a DSB in my display tank as well) releasing a HUGE amount of detritus, as well as worms/pods/micro critters - into the water column - feeding both my corals and fish.

    I repeat this process once every 1.5 to 2 weeks or so.....
