WebFish and other aquatic life require a pH range of 6.0 to 9.0, and because alkalinity buffers against rapid pH changes, it protects the living organisms who require a specific pH range. Higher alkalinity levels in surface water will buffer acid rain and other acid wastes, preventing pH changes that are harmful to aquatic life.

WebDue to this, hard water (which has high mineral content) usually has a high pH making it more alkaline. The high mineral content acts as a buffer hence reducing the amount of acid in the hard water. Likewise, soft water tends to have low mineral content hence it’s usually low in pH which makes it more acidic. Know Your Water Hardness WebThe other reason that hardness is important is that it affects pH. Hard water (high mineral content) is usually high in pH. Soft water (low mineral) is usually low in pH. The mineral in hard water will act as a buffer which will reduce the amount of acid in the water. The resulting water will be more alkaline and higher in pH. The problem ...
