Calcite is a high grade of naturally occuring calcium carbonate. This media is an inexpensive option for bringing acidic water to a neutral, less corrosive pH. One of the greatest advantages of calcite compared to other acid neutralizing medias is its self-limiting property. When applied correctly, will only correct the pH enough to reach a non-corrosive equilibrium, and will not over-correct and make the water too alkaline. Calcite neutralizer tanks are able to easily neutralize acidic water from 5.8 – 6.6 pH. Below this, a blend of calcite and FloMag Corosex media is recommended for best results.
