As the weather warms images of tank tops, shorts, summer festivals and lounging by the pool run through my head. However, a caveat to swimming pools can be all those chemicals. Hotels now are offering chemical free salt water pools. But what I’ve become interested in are natural freshwater pools that have no need for chemicals or salt. What these pools use are plants and their natural filtration system to do the same job as the chemicals and complicated, energy zapping filtration systems. And as a result, you get a beautiful, natural, sustainable oasis that’s actually fairly inexpensive to construct and requires minimal management.
