WebFish and other aquatic life require a pH range of 6.0 to 9.0, and because alkalinity buffers against rapid pH changes, it protects the living organisms who require a specific pH range. Higher alkalinity levels in surface water will buffer acid rain and other acid wastes, preventing pH changes that are harmful to aquatic life. WebTotal alkalinity is a measure in parts per million of all the alkali (all carbonate, bicarbonate and hydroxide ions) present in a sample. Therefore, total alkalinity is a measurement of …

WebTotal 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. Maintaining both pH and total alkalinity in your swimming pool is important for keeping your pool properly sanitized and non-corrosive. WebPhenolphthalein alkalinity (p-alkalinity, also Partial or Free alkalinity) is determined by titration to a pH of 8.3 (the end point when phenolphthalein indicator changes color) and it registers the total hydroxide and one half the carbonate present. Phenolphthalein alkalinity is a subset of total alkalinity.
