pH | Calcium | Alkalinity
Everything from weather to oils, dirt, and cosmetics affect your pool water balance - in short, anything that comes in contact with your pool water. A pool that is "balanced" has proper levels of pH, Total Alkalinity, and Calcium Hardness. Water will seek its own balance level, water which is under-saturated will attempt to saturate itself by dissolving everything in contact with it. Water which is over-saturated will attempt to throw off some of its content by precipitating minerals in the form of scale. How do we know when our water is over or under saturated? We use a good test kit (with fresh testing reagents) to measure the chemical levels of pH, alkalinity, and calcium hardness.
