I have a net with 3/4" openings and only have it for falling leaves and debris. I am kind of OK with the food chain stuff and my fish doubled in number the very first year, so a raccoon or two might be helpful! I put my net on in September, I think, and made it high on one side, so the leaves would slide down and not weigh down the net. Even though all the leaves have fallen, I still have the net on. We have some final blowing and yard clean up to do - as do some neighbors. Without the tall marginal plants up and growing, everything can get blown into the pond. Once everyone in our house gets and stays healthy, we can do yard clean up and I will take down the net. I'm looking forward to seeing everything in the Spring!
