When barley straw bales are placed in water, they begin to decompose. This process of decomposition is believed to release phenolic compounds and these compounds are believed to have a natural signature similar to that of hydrogen peroxide.

Safe for pets, fish and livestock, this concentrated liquid extract also won’t harm your aquatic plants or plants which are irrigated with the same water.

Whole Barley Straw Bales VS Barley Straw Extract

So, what’s the difference between the two? Simply put – it’s a different process when using whole Aquatic Barley Straw Bales. Whole Barley Straw Bales are manually placed and loosely bundled in water, while Aquatic Barley Straw Extract is poured into the water as a liquid. As Aquatic Barley Straw Bales can take up to 4-8 weeks to begin the decomposition process, Aquatic Barley Straw Extract may be used for the first 8 weeks along with the straw bales.
