Our Algae Control Package is a great way to control issues with filamentous algae and aquatic weeds. This package consists of a combination of algae control pellets, beneficial bacteria, and lake and pond dye. Algae control/barley straw pellets work by releasing compounds which inhibit the growth of filamentous algae, beneficial bacteria consumes nitrogen and phosphorus in the water column (the nutrients primarily responsible for weed growth in ponds), and dye prevents sunlight from reaching vegetation. By applying these three products together, you can significantly decrease the growth rate of algae and aquatic weeds in your pond. It would be best to apply this package in the spring to get a head start on your weed problem, with a second application occurring in early/mid 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 algae control pellets, 3 bags of beneficial bacteria, and 1 pouch pond dye.
