An alternative to chlorine pools, “Natural Pools” use plants to keep water clean and clear, reflecting nature’s own perfect cycle. These could prove invaluable in a grid-down situation, offering a natural habitat for needed flora and fauna, water filtering capabilities, and more!
Here is a collection of some natural pools to help jumpstart your creativity!
