Barley straw controls the growth of algae in ponds and fountains. When the barley straw is placed in ponds, it begins to decompose and releases lignins into the water. The lignins are then oxidized into humic acids, which in turn, produce hydrogen peroxide. The continuous release of hydrogen peroxide stops algae from reproducing and stops growth of existing algae.Depending on pond size, the straw can be used in bales, sprinkled in water as loose straw or conveniently packed into net bags. The amount of straw needed depends on the surface area of the pond. Approximately 1/3 ounce of straw per square yard of surface area is recommended. More may be used at first if water is already green and decreased once the algae is under control. Time needed to get algae under control depends on amount of algae already present in water and water temperature.
