Review: Kills weeds fast. - Great product, seller needs to make sure the caps are tight though. Glad they put it in a plastic bag.
Review: This stuff really works!! - This stuff is amazing. I have a lake in my backyard and every spring It starts to grow aquatic weeds. Also with the rains in April and May, it makes the water just kind of cloudy and yuck so I mix up a batch of this and it kills the aquatic leaves, but it’s safe for the fish. I also discovered that this stuff is lethal for any sort of regular weed. I was using regular weed killer and it would take a week or so to actually kill the weeds but never really just knock them out. So when I have extra of this stuff from the Lake. I put it on any weed that I want to annihilate. It kills them within an hour or so. I like that because they stay dead. They do not come back from this stuff. It is a little expensive to use as a total weed killer and you do need to have a soap or something so that it adheres to the weeds and you add it in your mixture when you’re using this... You use water, this stuff and I forget the name of what the soap thing is supposed to be called and you mix those three things together and you have your mixture. I get two batches out of each of these bottles. That requires two bottles of the soap stuff. I mix those in a sprayer and I’m good to go! This is good stuff!
