Suicide is the third-leading cause of death for young people ages 15 to 24. Approximately 20 percent of teens experience depression before they reach adulthood, and between 10 to 15 percent suffer from symptoms at any one time.
What is Alkalinity? Alkalinity is the water's capacity to resist changes in pH that would make the water more acidic. This capacity is commonly known as buffering capacity.
Related to pH, total alkalinity is a measure of the alkaline substances in the water. The pH depends on TA. When maintained at proper levels, pool water resists a change in pH. Hardness, on the other hand, is a measure of the calcium and magnesium in the water.
