Meridian Oolitic Aragonite Substrate - 19.8 lb.
Item # 233942 / Manufacturer Part # 3406
This aquarium substrate has fairly uniform 1/4 to 1/2 mm spherical or egg-shaped grains for reef and marine aquaria. The grains are aragonite, a naturally occurring calcium carbonate material made in the shells of many marine organisms. It has a superior buffering capacity to keep pH stable in a range suitable for most marine aquariums.

Dirty sand 8/27/2013
This sand was extremely dusty and had a lot of foreign debris. I had to wash it about 20 times to get the dust down to reasonable levels before adding to my tank.
