Right size granule
This is the exact size granule you want for algae control. Light enough that it doesn't penetrate the algae and sink to the bottom yet large enough to resist some wind from blowing the powder back for you to breathe.

It is not 99% copper sulfate
says on this article 99% pure copper sulfate on the bag they sent me says 5%. Very harmful to fish do not get in the lakes

Good Stuff
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.
