Barley Straw Extract works as an algae preventative. It does not kill existing Algae. Barley Extract works to slow the growth of algae cells without affecting any plants, fish, frogs, snails, turtles, pets, humans or waterfowl.
Barley straw extract is non-toxic, inexpensive to use, long lasting, low maintenance and has no water use restrictions and best of all, it works!
Barley Straw Extract works best by applying it before the onset of Algae growth.
If Barley Straw Extract is applied after Algae is present, it will take longer to see results. When pond water is pea green and/or Algae mats are floating on the pond or lake surface it will take higher than recommended application rates to be effective, and the use of an Algaecide product to kill existing Algae formations is recommended.
Available in 1-gallon containers.
