  Cloudy water in your CalderaSpas Hot Tub can stem from several causes. It could be due to a dirty filter, so cleaning it is recommended. Excessive oils or organic matter might be the issue, in which case, shock the spa with sanitizer. Improper sanitization can also lead to cloudiness, so ensure you add sanitizer. If suspended particles or organic matter are present, adjust the pH and/or alkalinity to the recommended range. Lastly, overused or old water can cause this problem; running the jet pumps and cleaning the filter can help.
