This product contains barley straw and humic acid. There are no chemical binding agents used in this formulation. Once exposed to pond water, these barley straw pellets will quickly begin to break down and release active ingredients that help to keep pond water clean and clear.

Apply 1 pound (approximately 4 cups) of barley straw pellets, per 1000 gallons of pond water, every 4-8 weeks. The barley straw pellets can be applied directly to the pond water, but for best results apply to the skimmer or filter.
