  Cloudy water in your Master Spas hot tub can stem from several causes. First, ensure that your filters are clean and that the filtration times are adequate. If the water chemistry is unbalanced, adjust the chemical levels accordingly. For suspended particles or organic materials, consider adding a spa clarifier, which you can source from your dealer. Lastly, if the water is old, replacing it might resolve the issue.

  If your Master Spas hot tub has a strong chlorine or bromine odor, it could be due to excessive levels of these chemicals. To resolve this, shock the water with a non-chlorine shock treatment. Also, check the pH level and adjust it if necessary, as a low pH can contribute to the odor.

  Eye or skin irritation in your Master Spas hot tub is often due to unsanitary water. Shock the spa with a non-chlorine shock treatment to sanitize it. Also, ensure that the free chlorine level is below 5 ppm; if it's higher, allow it to drop. Poor sanitizer and pH levels can also cause irritation, so adjust them according to your spa test strip results.
