Cutrine: Use this contact algaecide to control algae before it reaches the surface of the water. The pellets are broadcast directly on the submerged algae for easy application. Use 30 pounds for 1/2 surface acre. Apply early morning on a calm, sunny day. Early treatment in the spring when weeds begin to grow provides best control. Filamentous algae will usually require re-treatment for season long control.

Available in 12 or 30 lb. Bags.
