I previously had another company taking care of my pool and always had a really strong chlorine smell and my hair would get so harsh after swimming, I also often noticed white powder on the bottom of my pool. After changing to ASP I never had the same issue and come to learn that the white powder can be very harmful and was not being done right. They are very professional and really know what they are doing. My pool is well balanced now and I love that they send me a picture every time after coming. Definitely recommend!!!
