There may be a very small change in the pH of your softened water. It does not affect the day-to-day usage of softened water. For example, a water pH of 8.6 may be 8.5 after softening.
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.
