The Barley Straw Bundles have been developed to provide a natural, chemical free solution to clarity in ponds. Made from a matting of barley straw and natural cotton netting, Barley Straw Bundles have a large surface area allowing easy access of water and oxygen to the straw and free release of natural compounds. There are many open ends of straw all round the edges of each Barley Bundles which allows water to penetrate into the hollow stems, greatly speeding the breakdown process. Soluble carbohydrates released from the surface of the straw act on the monocellular green water algae causing them to clump together (flocculate) and sink to the bottom of the pond. In this way green water is often cleared in just a few days. Making the best use of the oxygen in water, safe aerobic decomposition is assured and the natural compounds which keep ponds clear are released into the water. The process continues for about six months giving long term protection.
Barley Pads plus Lavender have been developed as a result of further research by the Center for Aquatic Plant Management. It was discovered that lavender could be more effective as a natural algaecide than barley straw, but needed more oxygen to break down. Thus Clear Pond have combined the benefits of the two plant materials into the Lavender Pads.
