Thank you so much for your reply. I don't plan on using pucks..just bbb..but the neighbor gave me a couple to use while I was awaiting the installation of our pump. The water looks crystal clear now but I'm not sure what will happen after all of the rain we had yesterday. Had so much rain that the pool was overflowing. How is my chlorine? Haven't used the bleach calculator..not sure how to use it yet but have it downloaded to my desktop. What ppm should the chlorine read? Should I add more bleach 2nite or wait til tomorrow??
