As long as you contain it to you pond , It is GREAT FOOD for koi and goldfish, our fish LOVE it, and so do aquatic snails,and tadpoles. It also shades the under water, and seems to keep the water clean!! I had bad alge trouble till adding this to my pond, now No alge, and my water stays nice and clean and my fish are fat and healthy!!
