A greasy coating on the walls along the waterline of the spa is evidence that there is a saturation of undissolved materials in the water while a ring of rough patches may be a sign of scale. Most of the time, oils and lotions that enter the water via soakers can cause the greasy build-up and scale conditions are due to water balance issues. Please visit the Scale troubleshooting section for more info on that problem.
We want you to feel confident that you are using the best products and doing the right things to create a relaxing and enjoyable spa experience.
