As the fish waste and uneaten food decompose, phosphate is released as inorganic or reactive phosphate into the water. Reactive phosphate causes unclear water conditions in your pond. Use of PHOS-OUT will remove the needed reactive phosphate resulting is clear pond water. Water Clarity and Algae Control! Removes excess phosphate that cloud pond water Binds with inorganic phosphate to restore balance of pond water Helps to restore and maintain the natural balance of pond water

Using the cap to measure, add 25 ml for each 100 gallons (1/3 cup per 300 gallons) of pond water. For best results, pour into water flow for even distribution. A slight temporary haze may form as phosphate is removed. The haze will disappear in a few hours. Repeat treatment once a week or when testing indicates an increase in phosphate levels. One dose will remove 1.5 ppm phosphate. Safe for plants, fish, birds and other wildlife in and around ponds. Keep out of the reach of children. For garden pond use only.
