The Calcium Saturation Index is a helpful tool for testing your swimming pool's health. This tool uses a variety of measurements to gauge this health, and is actually quite simple in practice. On Pool Calculator we'll be diving into the CSI.
Interested in learning more about what it takes to keep your pool or hot tub in great shape? This article describes the chemistry involved in keeping your pool or hot tub safe and your water crystal clear. It will help you better understand what the tests you are taking mean, and what happens when your pool chemistry is no longer in the recommended ranges.
Maintaining both pH and total alkalinity in your swimming pool is important for keeping your pool properly sanitized and non-corrosive. Total alkalinity is to pH what cyanuric acid is to free chlorine. Total alkalinity stabilizes pH levels. The ideal pool pH level is 7.4 to 7.6. The ideal total alkalinity level is 80 to 120 ppm.
Swimming Pool alkalinity (often called total alkalinity) is a measurement of the concentration of alkaline materials in your pool. Alkaline materials stabilize pH but buffer chlorine sanitation.
Total alkalinity is important to test and maintain. However, total alkalinity is largely similar and even correlated to cyanuric acid. Therefore, it is not as volatile as free chlorine or pH levels and does not require as frequent testing. A reliable rule of thumb is to test total alkalinity every other time you test pH levels.
