Looking for some shiny black sand for your aquarium? Look no further because this stuff (med) is great in an aquarium. Super cheap compared to any black "aquarium sand". Just put some in a bucket and run a hose though it until the water is clear. Additionally you can add a few drops of dish soap at the beginning to remove any greasy residues. one year later and all my plants and fish are happy. Perfectly safe even for sensitive bottom dwellers such as Cory cats.

I bought this to use with a new media blaster. I have 1/8" nozzles, as my compressor isn't that big. The medium size will not pass through a 1/8" nozzle. I thought I was purchasing the fine. I think the media is fine for outdoor work, but watch your size...
