Maintaining the correct acidity level in spa water is crucial for bather comfort and equipment longevity. An elevated level indicates the water is too alkaline, potentially leading to scaling, cloudy water, and reduced sanitizer effectiveness. Addressing this imbalance involves introducing a pH reducer, typically a dry acid compound, to adjust the chemical composition of the water.
Proper water balance ensures optimal sanitizer function, preventing bacterial growth and protecting against skin and eye irritation. Historically, imbalances were addressed using various homemade remedies, often with inconsistent results. Modern chemical solutions offer a more precise and predictable method for achieving the desired water chemistry.
