Hi all, my name is Adam and I live in Oxford AL. I have opened my pool for 2 years in the past, skipped last year and I just got a new liner installed recently. I had no idea there was information like this available. I've always trusted the pool store folk. I can't wait till my test kit gets here and try to read as much as I can in the mean time. I want to thank everyone for providing this awesome service. I look forward to getting acquainted with you.
