Prevent debris from accumulating in your pond using pond netting. Using nets in and around your pond can help capture falling debris, as well as protect fish from predators. Pond netting often comes in a sheet or roll, designed to be suspended slightly above the water and supported by rocks or ground pegs, or can be a basket design attached to a handle. Netting sheets are often a permanent fixture in water gardens, remaining above the water year round. Handled nets are designed to be used to scoop debris or fish out of the pond sporadically, when needed. Most netting is black in color, to blend with the black liner, and comes in a range of sizes to meet your pond's needs. Keep leaves and other debris from entering the pond with a pond net.
