Why is the water cloudy in my CalderaSpas Hot Tub?
- NNicole HernandezJul 31, 2025
Cloudy water in your CalderaSpas Hot Tub can be due to several factors. It could be caused by dirty filters, so cleaning them is recommended. Excessive oils or organic matter might be present, requiring you to shock the spa with sanitizer. Improper sanitization can also lead to cloudiness, so adding sanitizer is advised. Additionally, suspended particles or organic matter may be the issue, necessitating an adjustment of the pH and/or alkalinity to the recommended range. Overused or old water, or excessive organics in the water, can also cause this problem; in these cases, running the jet pump(s) and cleaning the filters, or draining and refilling the spa, respectively, are the suggested solutions.
