This specially blended, multi-tasking formula manages swimming pool water while eliminating the confusion of adding multiple chemicals and testing every other day. SIMPLE BLUE contains a stable oxidizer, algae shield, clarifier, scale inhibitor, water conditioner and balancers (pH, Total Alkalinity, and Calcium Hardness) to keep swimming pool water clean, clear and trouble free. It provides a PROACTIVE water care program that PREVENTS problems instead of treating them on a REACTIVE basis after they occur.
