I joined this forum last year when I opened my pool up, I ran into some issues but with the things I learned on this website I was able to figure everything out. Now this year has been much easier and I haven't really had any more issues. I have the Taylor Fas-Dpd (as it was highly recommended) test kit and find it has been more reliable/accurate than a pool store where I had my water tested a couple of times last year. Anyway I just wanted to say thanks, you guys taught me what I needed to know to keep a clean and safe pool.
