Alkalinity is common baking soda. Hatawa
i believe its called alkalinity
1. M-Alkalinity (also known as Total Alkalinity) measures the amount of carbonate, bicarbonate and hydroxide present in terms of "ppm as calcium carbonate". ( M-Alkalinity measurement is based on a sulphuric acid titration using a Methyl orange indicator that goes from yellow at a pH of 4.5 to orange at pH of 4.4 at the endpoint.) 2. P-Alkalinity measures the amount of carbonate and hydroxyl alkalinity present in terms of "ppm as calcium carbonate". P-alkalinity is measured down to a pH of 8.3. The M-alkalinity is measured down to a pH of 4.3.
Phenolphthalein alkalinity measures the hydroxide ion concentration in water, specifically the amount that can be neutralized by strong acids. Total alkalinity, however, measures the water's ability to neutralize acids, including carbonate, bicarbonate, and hydroxide ions. In summary, phenolphthalein alkalinity focuses on the hydroxide ions, while total alkalinity considers a broader range of alkaline substances.
Alkalinity refers to the capacity of water to neutralize acids and is primarily due to the presence of bicarbonate, carbonate, and hydroxide ions. The main types of alkalinity include bicarbonate alkalinity, which is the most common form found in natural waters; carbonate alkalinity, which occurs at higher pH levels; and hydroxide alkalinity, which is less common and typically found in very basic conditions. These types of alkalinity play a crucial role in maintaining pH levels and supporting aquatic life.

To effectively remove alkalinity from water, you can use processes like reverse osmosis, distillation, or ion exchange. These methods help reduce the alkalinity levels in water by removing minerals and ions that contribute to alkalinity.
The word alkalinity is defined by the ability that any substance has at neutralizing when it is mixed with an acid.
To check the alkalinity in your pool, you can use a test kit specifically designed for measuring alkalinity levels. Follow the instructions on the kit to obtain an accurate reading.
Alkalinity is not an actual "chemical", however if you are concerned about increasing the alkalinity in your swimming pool, you are perfectly safe. The chemical that increases "total alkalinity" in a swimming pool, is only baking soda. It wil not harm the human body!
There are no perfect rhymes for threshold.
