    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...

    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...

    Great price

    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-

    4 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.

    Fine/red= sandblast; Medium/black= tank substrate

    4 months ago
    Seen reviews on this for tanks after using it in our gunsmithing shop for sandblasting firearms prior to painting. We use the red fine grit for the sandblaster and the black label medium grit for the tank substrate. Both work great and are SOOOOO MUCH MORE AFFORDABLE than other options. Definitely more bang for your buck in both scenarios!

    Yes, I recommend this product.
