Barley Straw Does Barley Straw Work To Keep Algae Down In A Pond? If So, Where Do I Get It?

Does barley straw work to keep algae down in a pond? If so, where do I get it? - barley straw

I have a pond that hold only under one hectare, and I have a heck of a time from the algae. The previous owner told me that the use of copper sulphate, I have in the local Bank AG, but it's pretty expensive and I several times a year, the pain is. I've heard that a construction soaking barley straw bales, but I do not know if this is true and if so, how and where to look for barley straw. (I live in northwestern PA.)
