A common indicator that a pool needs to be shocked is cloudy or green water. Shocking a pool involves adding a large dose of chlorine or other sanitizers to eliminate contaminants, algae, and bacteria that can cause water clarity issues and poor sanitation. When the water appears cloudy or green, it usually indicates that there is a buildup of organic matter, algae proliferation, or chemical imbalances that need to be addressed to restore safe and clean swimming conditions.

In contrast, clear water typically suggests that the pool's chemical balance is adequate and that the filtration system is working effectively, while cold water temperature alone does not indicate a need for shocking, and a low bather load means fewer contaminants are introduced into the water. These other conditions do not necessitate immediate shocking of the pool.
