Crystal Blue Copper Sulfate Crystals
8 days ago
Worked great! But, be careful.. it killed my bullfrogs in the tadpole with legs stage. I sprinkled it around the edge of my pond and they congregated in it to eat the the algae and plants and died. Don't use if you have new bullfrogs.

Copper sulfate kills pond weeds
a year ago
Kills weeds in our 1/2 acre pond. I use the boat, hand held whirly bird fertilizer gizmo. Wear safety goggles, mask, leather jacket, because copper sulfate is toxic. I float over the weeds and give it a sprinkle. After a few weeks plants should be brown. If you missed some go back for a second dose. Only do about 1/3 of the pond at a time other wise you can kill all the fish like I did one time.
