Shocking a pool can potentially raise the pH levels if the shock contains a high pH level, although it is not guaranteed. This increase in pH levels can lead to cloudy water and reduce the effectiveness of the shock treatment. Therefore, it's important to test the pool water after shocking and adjust as needed to maintain balanced pH levels. By adjusting for balanced pH levels, you can prevent issues such as cloudiness and ensure that your shock treatment effectively keeps your pool clean and safe for swimming.
