What is one method to quickly reduce cloudy water in a pool?

Adding a clarifier or flocculant is an effective method to quickly reduce cloudy water in a pool. These products work by binding together small particles that are suspended in the water, which are often too small to be filtered out effectively. When these particles clump together, they become larger and easier for the pool's filtration system to remove. This process not only helps to clear up the cloudy water but also improves the overall clarity and quality of the pool water.

Using chlorine might help with sanitization, but it does not directly address the issue of clarity. Simply draining and refilling the pool can be impractical and wasteful, especially for large pools. Increasing the water temperature does not contribute to resolving cloudiness and can potentially exacerbate issues in hot weather by promoting algae growth. Therefore, the use of a clarifier or flocculant stands out as the most efficient solution for this issue.
