What should be done if the pool water is not clear?

When pool water is not clear, the most effective initial response is to shock the pool and check the chemical balance. This approach addresses potential issues with water clarity that may stem from high levels of contaminants, such as algae or bacteria, which can cloud the water.

Shocking the pool involves adding a high dose of chlorine or other oxidizing agent to quickly eliminate these contaminants, effectively restoring clarity. After shocking, it's essential to test the water's chemical balance (pH, alkalinity, and chlorine levels) to ensure they fall within the recommended ranges for safe swimming. Proper chemical balance not only helps clear the water but also promotes a healthier swimming environment and protects the pool infrastructure.

In contrast, changing the water entirely may not be necessary and can be a waste of resources. Stopping pool use might be prudent if clarity is related to safety, but addressing the underlying chemical issues is a more actionable step. Lowering the water level does not directly address the root cause of water clarity issues, making it an ineffective response in this scenario.
