    Non-toxic Yellow Out will rid your pool of algae fast! Yellow Out is a powder-based treatment that designed to enhance the effectiveness of pool shock. It safely but quickly kills yellow, green, pink, or brown algae from pools gently without relying on harsh chemicals that can damage your liner or pool equipment. One 2 lb. bottle equals a single dosage for 15, 000 gallons.

    Follow the instructions for balancing your pool water and add the recommended dose into the water. Follow up five minutes later with a shock treatment, run your pump & filter system for 24 hours, and super chlorinate a second time to finish it off.

    Dosage: 2 lbs. per 15,000 gallons
