Barley Straw Extract


SKU: N/A Category:

Restore pond clarity, water quality and pond balance with CrystalClear Barley Extract. This powerful liquid barley concentrate works faster and cleaner than barley pellets or barley straw bales.

As barley straw slowly ferments or rots, it produces a natural extract which has been proven to clear pond water. While effective, this fermentation process has always been slow and messy requiring the barley to be added early in the spring. Designed to eliminate these steps, CrystalClear Barley Extract is fermented under ideal conditions capturing the powerful all-natural barley extract, allowing it to work immediately out of the bottle, with no mess.

Barley Extract is the natural solution to maintaining a clean and balanced pond all year long. Faster than barley pellets and cleaner than cumbersome barley straw bales, Barley Extract is a powerful liquid concentrate that goes to work fast. With Barley Extract, you can enjoy the benefits of barley straw without the mess and without the wait.
