Compatibility / Fitment Notes

Follow the product label and use a suitable test kit to determine when additional sanitizer is required.

Natural Chemistry directs users to ensure spa equipment is operating correctly, maintain pH between 7.2 and 7.6, and regularly test the water to establish and maintain 3–5 ppm available chlorine. Routine maintenance and superchlorination amounts depend on spa water volume and conditions, so follow the labeled dosage instructions rather than estimating treatment amounts.
