Does anyone know of a good way to get rid of snails without harming the plants. Copper will kill the snails ,
but it will also kill the plants It is a 30 gallon pond and I drained it several weeks ago, to remove the fish that were eating the plants instead of the mosiquito larva, and I thought I got all of the snails then. However, today I removed over 20 small black snails from my plants. They are able to float and seam to perfer eating the bladerworts instead of the algie on the side of the pond. I also have tadpoles and crayfish in the pond so I don't want anything too toxic.
