We recently built our first pool and we chose a freshwater system. After some research we decided on Enviroswim and we are so glad we did. Firstly the water is crystal clear and soft. My husband was a champion swimmer and he couldn’t believe how soft the water is to swim through. Plus no salt or chlorine to stick to your skin, let alone these chemicals penetrating our bodies. Our dogs love the water too as there can be no side effects from salt or chlorine on their skin.
