Hello tfp! We are about 2-3 weeks away from having our pool finished, and I am very excited to take care of our pool using the tfp method. I've already received my tf-100 test kit and speedstirrer. I was reading the instructions and am confused on when I'm supposed to use the speedstirrer. I know checking the fc and ph is a daily test but do I use only what's in the blue box or do I transfer to speedstirrer? I'm sure I will have a many more questions in the future, new to pools and testing. TIA
