Barley Liquid Extract

  • $49.99

Barley Straw Extract works as an algae preventative.  Slowing the growth of algae cells naturally without affecting higher plants, fish, frogs, snails, turtles, pets, humans or waterfowl. Barley does not kill existing algae growth. 

Barley straw extract is non-toxic, inexpensive to use, long lasting, low maintenance has beneficial effects, has no water use restrictions and best of all, it works!

Barley Straw Extract works best by applying it before algae start growing.

When the water is pea green and/or algae mats are floating on your pond, you will have to use an algaecide product to kill off the existing growth, then start with your Barley Extract treatments. 

Available in 1-gallon containers.
