    Aroganite is the best, but expensive and IMO playsand does the job just fine! Just make sure its washed plenty before adding it!

    you can add a cup of sand from a fellow reefers established DSB

    I see that you live in East London - in that case, real sea sand would be the best, IMHO. Just make sure that you get fine sand, and collect from below the low-water line off an unpolluted beach.

    If you collect wet sea sand, it will already contain some bacteria. You cannot really add them between layers - they will populate the entire sand bed.

    Here's some reading:

    As oom Hennie said collect from a beach where not many people go to, but go when the tide is at it's lowest preferably during a full moon is best as the further in towards the sea the finer the sand well suppose to be. I got mine at my grandparents farm in velddrif here on the west coast & nobody is ever on that beach besides some springbok or unless we go there & the bonus is that there's no litter or kelp to be seen for km. Also a leka place to get NSW but it's a shlep to move the water for easy 3km to the house on a sandy road unless using a tractor & then another 3 or 4 km to the gate on the same sandy road then only can hook trailer to the bakkie. Far too much pt but then there's the dirt buggy (the fun buggy a chassis,rol bar cage & motor oh & bucket seats) but the there will be no water or trailer left will be having too much fun & most definitely not road worthy.

    Use sea sand, you are close enough.

    There after play sand, do to it being cheap.

    Then Aragonite, but expensive.

    for a DSB, i personally would not go the expense of aragonite, sea sand as suggested is the most cost effective and natural option (after all mother nature cant be wrong if its working for her) :). be selective to grain size (sugar size grains work best) and be sure to check the sand by placing a magnet in a packet and running it over the sand. you will be surprised how much metal you will find.

    DSB must be 110mm deep at least and as much as 30cm is suffiecient, preferrably only have about 5cm distance between top of DSB and the water flowing over it..

    how big is your suggested DSB area?

    Ditto. And, generally, the finer the grain, the better.

    Just as a matter of interest for a DSB, I have dived on some reefs up this side and taken a container and collected aragonite looking coral sand. It is very, very alive and full of bugs and full of corraline growth... a little course but nice to sprinkle over the top of DSB's to 'seed' (or awesome for in a Display Tank!).
    Just an idea for reefers that have access to dive gear!

    i do the same and it works wonders in seeding the DSB and getting the excavation crew straight to work, then its just to wait for the anerobic bacteria to arrive to the party...

    If you're close to a mangrove estuary the very fine sand almost mud looking which could be found around the roots of the mangrove trees. That very fine sand would actually be perfect.

    Lucky you the very fine sand almost looking like mud also known as miracle mud. If you manage to find some that would make a little jealous as we don't have a mangrove estuary close by unless I take a drive to the EC. I hope you find it Good Luck

    You live in gonubie just go down to black rock at spring low next the the big black rocks and grab a bucket or ten full of sand it works super well.
