Selecting the correct pond liner starts with understanding your pond’s purpose. A decorative water garden may need less reinforcement than a deep koi pond or a pond with a waterfall. For aquatic animals, choose a fish safe pond liner that is specifically rated for fish and plant health. Flexible rubber liners adapt well to natural curves, while boxed preformed liners offer simpler installation. Consider local weather, soil conditions, and sunlight exposure as well. These factors affect durability and water retention.
