Southdown Homedepot Sand - Oregon?

You can pick up playsand at any Home Depot or Lowe's. Many will say if they are not approved for aquarium use, but you may want to ask someone that works there.

I used just aragonite playsand and had no problems... from what I have heard, Southdown is just playsand from the caribbean. If you have access to it, great. But if you don't... just get the next best thing....

And, if the grain size and color of the play sands don't appeal to you, you can use pool filter sand or sandblasting sand. I used pure white sandblasting sand and it's been working perfectly for about two years now.
