I have been following the TFPC method for several years. I still have questions at times and by no means do I feel like an expert! I went away for a week and a half. I had my pool clean and balanced before I left. Because of the TFPC method I understood the amount of chlorine it should consume and measured out the amounts. They were added at 2 times while I was gone and when I came home it was just how I left it. All I did was test the water and added the proper amount of chlorine. And tomorrow I will be swimming as if I never left.
