CircuPool Help Guides: Universal / Si Series pH - Acidity/Alkalinity pH indicates how acidic or basic the water is. pH should be tested daily at first. Once you gain experience with your pool, less frequent monitoring may be appropriate, depending on your pool's typical rate of pH change. pH levels between 7.5 and 7.8 are ideal, while levels between 7.2 and 7.8 are acceptable for swimming.
CircuPool Help Guides: Universal / Si Series BASIC WATER CHEMISTRY - PHOSPHATES & NITRATES Phosphates are a part of the environment: Phosphates became a household word in the 1970's. This is when people started to use low-phosphate and phosphate-free laundry detergents to help minimize the detrimental effects of excess phosphates in lakes, streams, wetlands and other runoff areas- effects such as unwanted algae blooms.
CircuPool Help Guides: Universal / Si Series BASIC WATER CHEMISTRY - LANGELIER SATURATION INDEX (LSI) LSI is a measurement of the water’s ability to absorb and hold solids in a solution. It is important to know that the scale on which LSI is measured is very narrow, meaning that a small change can indicate a significant difference in your pool.
