What is the difference between Southdown and playsand? What makes it better for a tank?
I'm upgrading my 28 to a 55 so I'll need more sand and I want to get get what's best.
Thanks!

Yes they do. Mostly silica playsand and those that are calcium carbonate based like Southdown, Yardright and Old Castle playsands.
What do you think your glass tanks are made out of? :)
Southdown has a variety of grain sizes that make a very good mix for a sand bed, and since it is ootlic, aragonite, cheap, and the fact that it is a bright white in the tank, it is the prize that many seek to keep cost down, and have a beautiful substrate.

So I can go to toy's r Us and pick this stuff up. I wonder? I always thought go to LFS and buy only argonite sand. Which is better white or black sand?

after you get it into you tank... i suggest populating it with all of the beneficial creatures found on the reef (well at least a small portion of them)
here is my little write up on sandbeds with some southdown info [/B]
Good info Kip! Since I'm upgrading the 28 to the 55 all the existing sand will come over too. I will need to add a lot of sand to get the bed to 5-6 inches. Any ideas on who carries Southdown in the Southern New Jersey area?

What about Tropic Isle Tahitian Moon Sand? I know it isn't argonite but is there any reason not to use it (like silicates etc)??

I guess it is volcanic since it's black and has a shine to it. It says "safe for mairine and fresh water aquariums" but that doesn't mean much. :notsure:
