Pure Calcitic Limestone

Calcitic limestone is calcium carbonate, and it neutralizes acids in the growing medium.

Calcium Carbonate provides some calcium, but almost no magnesium. Calcitic limestone dissolves faster than dolomitic limestone so it quickly adjusts a growing medium's pH within one week, but it has a shorter residual effect of up to 1-2 months.
