Our Algae Control Package is a great way to control issues with filamentous algae and aquatic weeds. This package consists of a combination of barley straw pellets, beneficial bacteria, and lake and pond dye. Barley straw works by releasing compounds which inhibit the growth of filamentous algae, while beneficial bacteria consumes nitrogen and phosphorus in the water column (which are the nutrients primarily responsible for weed growth in a pond), and dye prevents sunlight from reaching aquatic vegetation. By combining these three items into one package, pond owners can significantly decrease the growth rate of algae and aquatic weeds, making for a more functional and attractive body of water. It would be best to apply this package in the spring in order to get a head start on your weed problem with a second application occurring in early summer. Packages can be applied at any time of the year but the bacteria is most active above 50 degrees F. Each package is capable of treating a 1/3 acre pond and consists of: 40 pounds of barley straw pellets, 3 bags of beneficial bacteria, and 1 quart of lake and pond dye.
