let me start out with so fat my water has been doing great with the basic kit I got form the PB.
My chlorine was around 2.8 when the pool store guy told me to super chlorinate with my SWG and raise the output from 10% to at least 45% as we are getting hotter here.
Well, my TC test went to dark orange to brown after and I knew the water was messed up.
So I ordered a TF-100 kit and here are my numbers today:
Turned the SWG to 0% to get the TC down and will test every other day.
