The pH value is an important element in a pond environment. The value is also determined by the amount of carbon dioxide (CO2) in the water.
If the pond water contains enough carbon dioxide, then the pH is relatively low (7 to 8). If there is little or no carbon dioxide, the pH can reach values ranging from 9 to 10. In order to reduce the pH value of the pond water Velda has created the product pH Min.
