    Q: Can this be used to rough grind rock in a tumbler

    9 days ago
    1 Answer
    • A: Howdy neighbor! While Black Diamond Medium Blasting Abrasives can technically be used in a tumbler, it is not recommended for a rough grind because the coal slag material breaks down too quickly and is not hard enough to efficiently shape rocks.

    Q: Is this one able to etch glass mason jars and not peel off the stickers that are on them

    20 days ago
    1 Answer
    • A: The Medium blend will be far too aggressive for this application. The Fine blend might work on the glass but would likely remove the stickers. We would recommend testing a small area if possible.

    Summary of Reviews

    AI-generated from customer ratings & reviews, and may include incentivized reviews.
    The Black Diamond blasting media can be effectively used as an aquarium substrate. Many customers report it looks great in fish tanks, is easy to clean, and provides a good environment for aquatic life. The medium-sized grit is well-suited for this purpose, though the coarser grades may be too rough...

    Great aquarium substrate!

    10 years ago
    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.

    Watch your size...

    10 years ago
    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...

    Very good price, but it doesn’t flow as good as sand for blasting. Can’t use sand anymore due to health hazard.

    Black label/tank substrate-

    6 months ago
    This is my second purchase of this for substrate in a 55 gallon aquarium! So affordable, I fill a 5 gallon bucket about 4 inches from the top and let water rinse throughout until water is clear and no longer showing any film on top, then I place it into the tank with a scoop. 1 bag was enough and it looks so good!

    Yes, I recommend this product.
