Calcite is the most thermodynamically stable under ambient conditions, but other polymorphs can form under specific kinetic conditions. Aragonite is more soluble and denser than calcite. It usually forms needlelike orthorhombic crystals and is favored at high temperatures and pressures. It is metastable, converting slowly to calcite.

information for you about pH in Drinking Water

An acid neutralizing filter uses a calcite or ground limestone (calcium carbonate) for normal pH correction, but could also include a blend of magnesium oxide and calcite, if the pH is very low. Since the water absorbs these minerals when it passes through the filter, the alkalinity and hardness will increase.
