What is the main reason for testing the pool's water quality regularly?

Regular testing of the pool's water quality is crucial primarily to ensure safety for patrons. The health and safety of individuals using the pool depend on proper water balance, which includes monitoring pH levels, sanitizer levels, and total alkalinity. Poor water quality can lead to various health issues, such as skin irritations, infections, or other illnesses, particularly if contaminants are present.

While maintaining aesthetic appeal and keeping pool equipment functioning are important considerations, they do not take precedence over the safety of individuals using the facility. Monitoring chemical costs, although relevant from a budgetary standpoint, is not a fundamental reason for testing water quality. The top priority for any pool operator should always be the well-being of pool users, making safety the primary motive for regular testing.
