In Europe, natural swimming pools are an increasingly popular alternative to chemically maintained pools. Plants act as a natural filter and harbor beneficial bacteria to keep the pool clean. No chlorine or salt needed. in garden homesteading ^^
Natural Swimming Pond Designs from Gartenart - I LOVE this idea! No chlorine, the plants at the edge keep the water clear and you swim. I am seriously torn between this and an inground concrete stained pool.
