Get that crystal clear pond or lake you have always dreamed of by using Copper Sulfate as an algaecide to control the Filamentous and Planktonic algae in your water.  Finally get rid of that nasty swimmers itch and enjoy the water once more.

Discovered in the early 1900's Copper Sulfate has been used for effective algae control in lakes, ponds, ditches, pools, golf course water hazards and irrigation routes. Its blue colored granules broadcast evenly or you can dilute it in water for even distribution.

Copper Sulfates works by binding to the proteins in fungi and algae causing them to leak and die off.  It is most effective when used on the bottom mats and first application should be performed as early in the season as possible to kill off existing shoots and prevent others from sprouting. This small 5lb package is great to use in smaller bodies of water such as watering troughs and pools, keeping clean and clear water all season long.

Copper Sulfate is not as effective in hard water as chelated products and is also toxic to fish in soft water areas.  It is corrosive to metal equipment, thus it should be used with caution. Apply 2.7 lbs. per acre foot of water. There are no restrictions on immediate water usage.
