Algae in a garden pond is an unsightly nuisance, choking plants and even killing fish. Barley straw flakes are the organic way of controlling most common algae. Use Barley Straw Flakes all year round for a healthy, clean and clear pond environment.
Enzymes released from the wet Barley Flakes act on green water and blanket weed and duckweed. The superior surface of barley flakes ensure faster more effective results.
