    imageHow do I apply Algae Shield correctly? 1 Answer

    • For best results: Run your circulation pump and filter so water is moving. Measure the appropriate amount of Algae Shield based on your pool volume: Initial treatment (no visible algae): 80 mL per 10,000 L (≈2,642 gal) of pool water Weekly maintenance: 30 mL per 10,000 L (≈2,642 gal) of pool water Visible algae (without superchlorination): 120 mL per 10,000 L (≈2,642 gal) Broadcast the liquid evenly around the pool while circulation is running. You can return to swimming about 15 minutes after treatment once the product has dispersed.
