Caribsea bulk sand are bags of sand that have been damaged in transport, or have been re-packaged. This is the exact same sand as the regular caribsea, just not in pretty packaging. Limited quantities available.
0.5 - 1.2mm diameter grain size (approximate).
Also known as "oolitic sand", this product is ideal for shallower beds, allowing denitrification in as little as 1" depth.
The fine grain size can pass easily through the gills of gobies and other sand sifting organisms.
The smooth round grains are gentle to soft bellied sharks and rays.
White in color and metal free, no ash or silica.
