What happens when the PH of a pool is not balanced?
Question Date: 2004-05-25
Answer 1:

The pH level indicates how acidic or alkaline the water is at any given time. A pH level of 7 means that water is neutral; above 7 means the water is alkaline, while below 7 indicates acidity. You should aim for a pH level of between 7 and 7.8. If the water pH is higher than 8, anyone who swims in the pool is at risk of skin rashes, while a pH of lower than 7 can sting the swimmers' eyes, and even cause a sore throat. When the pH or alkalinity too high you might see calcium in high contents causing scale deposits. Also, you might get Cloudy or Dull Water. Stains and rust might accumulate when the pH is unbalanced too.
