Poolife Back to Blue Shock System (4.6 lb)

Back To Blue is an amazing 2 part system designed to turn your green pool back to blue. Back to Blue works in as little as 24 hours to stop your algae bloom and get your pool water back to crystal clear. For best performance, swimmer comfort, and crystal clear water: Maintain pH in the range of 7.2 to 7.6. Maintain total alkalinity in the range of 60 to 120 ppm. Maintain calcium hardness above 200 ppm. Use a Poolife test kit that measures all these ranges. Re-entry into treated pools is prohibited above 4 ppm due to rush of bodily harm. If you are experiencing a sever algae bloom, which has turned your pool green, the Poolife Back to Blue Shock System can turn your pool sparkling blue again. This two-part system destroys the bacteria and algae that have taken over your pool and then makes it easy to vacuum out. At the start of the season, or if a sever algae bloom occurs during the season, the pool can be treated and returned to its clear blue appearance within 24 hours by using Poolif
