Leslies Algae Control Pool Algaecide and Algae Preventer

Directions

Routine Usage Directions for Swimming Pools

• Leslie’s Algae Control is used to control the growth of algae in swimming pools, exterior spas, whirlpools, hot tubs, decorative fountains, and containerized ponds that do not contain fish. For maximum effectiveness, pools, spas, whirlpools, hot tubs, decorative fountains, and containerized ponds containing heavy growth of algae must be cleaned prior to use.
• For pools having just visible algae growth, add an initial dose of 11 to 16 fluid ounces of Leslie’s Algae Control Pool Algaecide and Algae Preventer per 10,000 gallons of water and remove settled algae.
• For treatment of freshly cleaned and filled pools, add 6 to 11 fluid ounces of Leslie’s Algae Control per 10,000 gallons of water.
• Subsequent additions of 2 to 4 fluid ounces of Leslie’s Algae Control Pool Algaecide and Algae Preventer per 10,000 gallons of water must be made every 5 to 7 days after initial treatment for maintenance.

Routine Usage Directions for Spas, Hot Tubs, and Water Features

• Spas, whirlpools, hot tubs, decorative fountains, and containerized ponds having just visible algae growth require an initial dose of 1 to 2 fluid ounces of Leslie’s Algae Control per 1,000 gallons of water.
• For treatment of a freshly cleaned spa, whirlpool, hot tub, decorative fountain, or containerized pond, add 0.6 to 1.1 fluid ounces of Leslie’s Algae Control per 1,000 gallons of water.
• Subsequent additions of 0.2 to 0.4 fluid ounces of Leslie’s Algae Control must be made every 5 to 7 days after initial treatment for maintenance.
