A secondary school revision resource for OCR Gateway GCSE Triple Science about chemistry: Hardness of water Hard water (high mineral content) is usually high in pH. Soft water (low mineral) is usually low in pH. The mineral in hard water acts as a buffer that combats aridification in the water. The resulting water will be more alkaline and higher in pH. Some species of fish require hard water while others require soft. Without the Correct Water Hardness, You Can't Fix pH Levels The problem arises when we try to lower the.
