It looked like we would save a lot on chemicals according to the information we could find on Enviroswim and this had been well and truly proved so far. Only needed some acid (lowering pH) and buffer/sodium bicarb (raising alkalinity) which would be needed in any pool. We had some landscaping delays in the beginning resulting in a lot of sand and rubble getting in our pool for nearly two months. Despite all this the pool remained crystal clear and swimmable at all times. The fresh water taste and feel is simply amazing, straight out of a late night dip, dry off and into bed. No salty/crispy feeling or chlorine smell, it like getting out of the shower.
