We are opening the pool, and I need help with the TFP method. What products do I need to buy? Last year we used 3" chlorine tablets, but I would like to use simpler products and save money. I have test strips that measure FCL, Alk, pH and CH. I know I need a new test kit, but I want to get started now. Currently, the water is reading 0 FCL, 80 Alk, 6.2 pH and 0 CH. Thank you for your time and energy into responding to me and helping me learn this pool stuff!
