The poolife® Back to Blue® Shock System can turn pool water from green to sparkling blue again. This two-part system (shock and flocculent) destroys the bacteria and algae that have taken over, then makes it easy to vacuum up waste. At the start of the season, the pool can be treated and returned to its clear blue appearance within 24 hours by using poolife® Back to Blue® 1 and poolife® Back to Blue® 2 as part of the poolife® Back to Blue® Shock System.
