  • Product Details

    • Available in 50 oz. (6 units in a case), 2.5 (2 units in a case), and 275 gallon containers
    • Active ingredient: Acid Blue 9 and Acid Yellow 23

  • Application

    Treating at 0.8 ppm controls most underwater aquatic plants. Using a rate of 1.5 to 2.0 ppm will provide better control in shallow waters or where plants are within 2 feet of the water surface.​
    ​
    Pour directly into water. Dispersion can be accelerated by applying in several areas around the treatment site, or allowing fountains/aerators to run. 
    ​
    For best results, apply early in the season, prior to plant germination. ​
