Natural swimming ponds do not require traditional filtration systems with chemicals but rely on biological filtration to maintain water quality. A well-designed pond uses a regeneration zone filled with aquatic plants and beneficial bacteria to absorb excess nutrients and break down organic matter. Water circulation, often aided by a small pump or gravity-fed system, helps distribute oxygen and prevent stagnation.
The natural balance of plants, microorganisms, and proper design keeps the water clear and safe for swimming. While some systems may incorporate skimmers or sediment traps to remove debris, the primary filtration occurs through natural processes.
