Well, we had zero experience with pool care so we hired Ryan. He showed up once every other week on average and our pool never turned green so we thought we were ok. Well, we started noticing brown marks on the bottom of our new, y re plastered pool and got a second opinion from Shasta and tested our water. Turns out Ryan had only been tossing in chlorine tabs and nothing else. We had to drain our pool, acid wash it(less than 6 months after it was re plastered), our pool system was corroded because he had been placing the tabs in the drain collectors which caused acid build up and erosion of the tank/system. Save your time and money and go elsewhere!
