Good afternoon, all. I am new to the forum, but not to ponds having had Koi ponds for years. But this is my first encounter with a regular outdoor pond. I live in a development that has two ponds, the larger is about 0.45 acres and the smaller, about 0.17 acres. I have been advised to control weeds with Reward, which I purchased. Now the big question. Each pond has a fountain. I read that I should use about, say 0.4 gallon in the larger pond. Since there is a big fountain in the middle of each pond, can I just walk around the pond and pour 0.4 gallon in the larger pond, and correspondingly less for the smaller one, and presume that the fountain will disperse the product?

Thanks
