Our natural swimming pools are also education for kids and adults alike. As the ecosystem builds and establishes itself, nature does its thing. In no time frogs, dragonflies, bees, birds etc will appear and create the natural calming atmosphere we all seek from time to time. Every day there is something new to look at as the plants grow and the fish and frogs breed. This is another major advantage over-chlorinated swimming pools, once installed they continue to change and become more beautiful at they grow and settle into the landscape.
