Barley straw extract is used for keeping water in ponds clear and free of excess algae.
Barley straw concentrate has been used for decades to help maintain water clarity and control excess algae. While the process is not fully understood by science, according to a paper published by Carole A. Lembi, professor of botany and plant pathology at Purdue University, it is believed to help maintain a balance between algae and the conditions under which they thrive. Barley straw concentrate is not an algaecide and therefore does not kill algae, reports the website The Pond Guy. Rather, it is used to reduce the rate of algae growth.
Instructions
1. Shake the container of concentrate to mix the solution well. There may be some sediment.
2. Measure 1 oz. of barley straw concentrate for each 500 gallons of water.
3. Pour directly into the water. If the water is cloudy or turbid, repeat in seven days and every seven days thereafter until the water clears.
4. Repeat the application every three months after the water has reached the desired level of clarity.
