What is pH ideal range commonly cited for optimal swimming conditions?

The ideal pH range for optimal swimming conditions is commonly cited as 7.4 to 7.6. This range is critical for maintaining comfort for swimmers and ensuring proper disinfection of the pool water. A pH level within this range helps to minimize irritation to the eyes and skin of swimmers, which can occur at higher or lower pH levels. Additionally, maintaining a pH within this range ensures that chlorine and other disinfectants are effective in killing harmful microorganisms without causing issues such as chlorine smell or reduced effectiveness.

When the pH is too low (such as in the range of 7.0-7.2), it can lead to corrosive water that may damage pool equipment, surfaces, and even harm swimmers. Conversely, a higher pH (like 7.8-8.0 and above) can lead to cloudy water, scaling, and decreased effectiveness of chlorine, requiring more chemical balancing and maintenance. Therefore, keeping the pH at 7.4 to 7.6 is essential for ensuring a safe and pleasant swimming environment.
