Since Foothills Poolwater Revival recycled and filtered our pool water and balanced the chemicals, our pool water has never been so clear. This newer technology eliminates the need and expense of draining the pool regularly to clear up the hard water buildup of calcium and other chemicals. The process is very eco-friendly as it conserves nearly all the water in the pool. The owner, Joan Whitmore, took great care in monitoring the entire process, was wonderful to work with, and gave us a detailed water analysis report based on before and after the filtering process. I definitely recommend Foothills Poolwater Revival.
