A pond liner plays an important role in maintaining the water quality in a natural swimming pond. By preventing water from seeping into the ground, the liner helps keep the pond’s water level stable, which is crucial for the plants, fish, and beneficial bacteria that filter and clean the water naturally.
A good liner also helps maintain a healthy ecosystem by keeping the water contained, allowing for proper circulation and filtration. If the liner is damaged or not installed correctly, it can lead to water loss, which disrupts the balance and could cause problems like stagnant water or poor oxygen levels. The right liner, especially one made from eco-friendly materials like RPE or EPDM, supports a healthy, chemical-free environment, allowing the pond’s natural filtration system to work effectively.
