Ben makes a beautiful Organic Pool with guidance from David Pagan Butler, Organic Pool inventor. Organic Pools keep the water clean without using chemicals. Instead, plants and animals and a bubble powered circulation system filter the water. Ben has used larch throughout the construction to create a natural, soft and warm feel to the pool. A life enhancing symphony of wavy wood and bubbling water. David Pagan Butler’s Natural Swimming Pools DVD is available from Green Shopping.
