Water flow through the barley straw helps to destroy algae. It also oxidizes the nutrients that algae live thus reducing their food source.           The barley straw is packed into 7 lb. mesh bags, average needed is  .1 lb. to 1 sq. surface yard of your pond. 

We sell bags that are 39” x 15” and can be anchored into shallow water. Then in the fall, pull them out and put the straw in the compose pile and the mesh in the garbage. Don’t put barley straw bales into the pond as they break and become a large mess and decompose into more nutrients the following year.
