Since the bacteria and algae are dead it makes it easy to vacuum out of your pool. At the start of the season, or if an algae bloom occurs during the season, the pool can be treated and returned to its clear blue appearance within 24-hours by using Back to Blue I and Back to Blue II as part of the poolife Back to Blue shock system kit.

• All-in-one: chlorinates, shocks and kills algae
• Restores water clarity
• Use only with filters that allow vacuuming to waste (bypass filter)
