Works immediately out of the Bottle

The powerful liquid barley concentrate works faster than and is cleaner than barley pellets or barley straw bales. As barley straw and pellets slowly ferment or rot, they produce a natural extract which has been proven to clear string algae. While effective, this fermentation process has always been slow and messy.
