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.
