Monitoring total dissolved solids (TDS) in a pool is crucial because elevated levels can lead to several issues, including equipment malfunction and skin irritation. TDS refers to the total concentration of dissolved substances in the water, which can include salts, minerals, and other contaminants. When TDS levels are too high, it can affect the water chemistry, making it difficult for sanitizers, such as chlorine, to function effectively. This can result in ineffective sanitation, leading to potential health risks for swimmers, as well as contributing to cloudy water and reducing the efficiency of filtration systems.

Additionally, high TDS can cause scaling on pool surfaces and in the equipment, leading to damage and increased maintenance costs. Thus, regularly monitoring and managing TDS levels helps ensure the longevity of pool equipment and enhances swimmer comfort, reducing the chances of skin irritation caused by imbalanced water chemistry.

The other options address various aspects of pool chemistry but do not fully capture the broader implications of TDS on overall pool health and swimmer safety.
