As barley straw decomposes in water, it releases lignins, which oxidize to humic acids in the presence of oxygen. If sunlight then shines on the humic substances, hydrogen peroxide is formed. The peroxides in turn help to keep your pond clean and clear. Barley straw pellets release a constant supply of low levels of hydrogen peroxide which is safe and effective. Start using Barley Straw Pellets anytime and apply every six weeks through fall.
