Aquascape Protective Pond Netting keeps debris and predators from entering the ponds, waterfalls, and other water features. Keeping leaves and other debris out is important to help keep your water feature clean, clear, and healthy. The netting can also be used to keep pond fish safe from predators, such as herons. The poly material resists tearing and is designed to be used year after year. Aquascape pond netting comes conveniently rolled with fourteen included U-shaped stakes to keep the net securely in place.
