CaribSea Black Sand 60lbs
 

I finished my tank build and I have 3 bags of sand left over.
The color is called Hawaiin Black and it is the arag alive line from CaribSea. I used this in my main display and it looks very cool since it is not the typical sand you see in everyone else's tank.
The sand is also wet in the bag, not damp like other sand I've used, which keeps down the cloudiness when you add water. Also it could be added to an existing system as well. It's hard to find, I had to order it online and have it shipped
3 x 20lb bags.

$100.....Pending
