High quality Pure Calcite Marble.

This is the highest quality calcite you will be able to find in Australia. The high quality ensures that you will see more consistant results with pH regulation with acidic water. Calcite will raise the pH of acidic water (5-7pH) to approx. 7.2pH

NOTE: Calcite will only have its pH buffering effect if the water is above 5pH. Any lower than this and the calcite will not work. To fix this you simply need to use a pH booster to raise the pH from below 5 so the calcite will work.
