How Does Barley Straw Work? Barley straw prevents the growth of algae. It does not kill existing algae. Because of this action, it is sometimes called an algistat as opposed to an algicide.
How long does barley straw take to work in ponds? Depending on the type of barley straw product you're using, the quality of your filtration, and how much aeration you have in place, the full decomposition process usually lasts between 4 to 6 months.
Once the straw has been added to the water it starts to decompose. This can take anything from 2 to 6 weeks, dependant on the temperature of the water, as the warmer the water temperature the quicker it breaks down.It is at this time that it is believed by many that by using oxygen which appears naturally in the pond water, the Barley Straw cells are released into the water, oxidate into Humic Acid, which is then converted into low level Hydrogen Peroxide which disturbs the growth of new algae cells, therefore removing the green algae from the water.
