We purchased our pool last summer and are very pleased we went with Enviroswim after being recommended by a few friends of ours. The water is less harsh than our tap water which is great for swimming, no need to wash bathers or even wash hair nearly as much. Our kids choose to have a swim rather than a shower in summer which is so convenient. As far as maintenance, pretty much I only need to check weekly and add a little acid so very time efficient. Great to swim in, easy maintenance, reduced pump running costs. All positives.
