Algae Shield® is a liquid algae prevention product intended for use in swimming pools. Algae Shield® should not be used in pools treated with Baquacil*, SoftSwim** or other biguanide products, or pools maintained with PristineBlue®. Algae Shield® should not be used in conjunction with other algae treatments, flocculants or metal-out products.

Algae Shield® works within a wide pH range, but for bather comfort, maintain the pH between 7.2 and 7.6 or as recommended by your swimming pool retailer.

If algae is already visible in your pool, send Algae Shield® to the Rescue!

1. Add Algae Shield® at a rate of 2 ounces per 1,000 gallons
    of water.
2. Run filter constantly for 48 hours.
3. Add a standard chlorine shock to oxidize any dead algae.
