Calcite / Marble Crushed Media (CaCO3) Description:
a) A common mineral consisting of crystallized calcium carbonate; a major constituent of limestone. Calcite is a crushed and screened white marble media which can inexpensively be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent. It is a naturally occurring material. It provides slower reaction for controlled pH correction.
b) Highly variable in form and color, calcite is best recognized by its relatively low hardness (H = 3) and its high reactivity with even weak acids, such as vinegar. When acidic water reaches neutral pH, no more calcite is dissolved. Additional technical information is at this link.

b) Calcite has a wealth of uses: as a flux in steel production and in processing of non-ferrous metals; in bricks, mortar and concrete for construction; as a raw material in glass; in the construction of roads and dams; in the manufacture of paper, paints and dyes, carpeting and other floor coverings; and in the treatment of water, industrial waste, gases and household refuse. It is also used to reduce soil acidity in agriculture, to absorb water and add calcium in food products, and in sugar
extraction.
c) Calcite is a versatile additive for use in a wide range of plastic and elastomeric applications. Its regular and controlled crystalline shape and ultrafine particle size together with the hydrophobic surface coating, combine to the benefit of both polymer processing and subsequent physical properties.
