Product Code: YWBSSING
Bagged barley straw to treat 3000 litres of water for up to 4 months. Barley Straw takes 2-4 weeks to activate and must be placed in the water ideally before the algae problem starts. Oxygen is essential for the process and the best place for the barley is on the water surface near a waterfall or pump outlet, if available. A piece of garden twine or string can be used to secure the barley to the edge or base of the pond. Replace the barley after four months.
