I have owned a pool for the past 3 years, but paid a company to take care of the maintenance. Due to financial circumstances, I need to start taking care of the pool myself. Single mom of 3 with a busy life and terrified of turning my pool green and not being able to swim this summer. I ordered the TF-Pro test kit, said a prayer and here we go. I am very grateful for this forum and anticipate having several questions come arise.
