How to build a natural swimming pool

A natural swimming pool is an exciting addition to a garden. It is the ultimate play resource that provides a healthy, chlorine-free environment for swimming, a living ecosystem for nature lovers and whole new world of aquatic plants for gardeners. This practical handbook describes a wide range of pools from simple "swimming ponds" to models with separate plant regeneration areas, and others that resemble traditional pools. It explains how plants are used to keep the water clean and advises on pumps, skimmers and filters to limit the growth of algae, encourage the growth of biofilm and keep the water sparkling. Natural swimming pools are easy to maintain, have low running costs and require less fill-up water than conventional pools.  This book provides tried-and-trusted advice on a feature that is increasingly in demand among aspirational, eco-minded gardeners and designers.
