This oolitic sand, Dry Aragonite Sugar Sized Saltwater Sand 30 lb by CaribSea, is ideal for shallower beds, allowing denitrification in as little as 1in depth. The fine grain size can pass easily through the gills of gobys and other sand sifting organisms. The naturally spherical grains are gentle to sharks and rays.
Grain size 0.1 - 1.0 mm.
