    Hayward Pro-Grid Vertical

    I did the install... A bit gun shy as first. Filter is running after 2 weeks on no filter and the pool is Crystal Clear and better than ever. The woman at E-Z that helped me was terrific, friendly and engaging. I shouldn't say this but we ending up chatting a bit. Great! Thanks... Bob P
