Chemically, the difference between the two is that hard water contains calcium and magnesium ions, while soft water does not. Soft water is easier to lather with than hard water is. Continue Reading.
Well water from areas which have a lot of limestone (calcium) is often hard. Water that comes from lakes and rainwater is often devoid of minerals, making it soft. It is important to understand how water hardness affects pH in your aquarium. 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.
