API EZ Spa® EZSTC1 1 lb Total Care Multi-Function Granular Compound for Spa Water 12 per Case. EZ SPA® is a water care program that combines simplicity and incredible water quality in a once-a-week application. This specially blended formula manages spa water while eliminating the confusion of adding multiple chemicals every other day. EZ SPA® TOTAL CARE contains a clarifier, stable oxidizer, scale and stain inhibitor, water conditioner, and balancers (pH, TA and CH) to keep spa water clean, clear and trouble free. Spa water treated with EZ SPA® TOTAL CARE is odor and foam free. The concentrated formula creates a PROACTIVE water care program that PREVENTS problems instead of treating them on a REACTIVE basis after they occur. EZ SPA® is compatible with ozone and mineral purifiers as well as traditional sanitizers and balancers.
