Green Vista's Barley Straw Extract Super Liquid uses the power of all natural barley straw to support clean aquatic environments and keep water quality at it's best. It is scientifically formulated to help maintain a natural balance in pond water and to help prevent unwanted build-up of algae in the pond and on submerged surfaces.

This concentrate is made from all-natural, organic barley straw, so it is safe to use with fish, pets, and aquatic plants. Barley is an algae-inhibitor not an algae killer. It is intended to prevent the growth and spread of new stringy/mossy algae,  so remove as much algae as possible before starting the treatment for best results!

Instructions:
Apply 1 oz. (30 ml) per 1,000 gallons of water.

Begin applications in the early spring and continue through entire growing season.

For best results: Treat once per week in Spring and taper off to once per every 2 weeks by Summer.
