We use copper sulfate to control algae in a 12 acre lake and use about 4-50 pound bags a season. Copper Sulfate from Amazon/Earthworks is always the right granularity we need/order and is shipped quickly. Earthworks customer service was great the only time I have had to contact them.
After properly mixing the copper sulfate and adding it to my pond I can now say that all of the algae is dead and the water is crystal clear. Good stuff!!!

Age control
Now that I know how to use it, it's just what we need to control age in our ponds.
