Thanks All,
Yes, I use Leslie's basic DPD kit (R-0001, R-0002, R-0014) for FC testing and the HTH 6-way kit for TC and then using grade school algebra I can determine CC. :-D Someday I will get a "proper" kit but I think for now it would only get me FAS and a rather useless acid demand test over the kits have now. Also, I'd rather use that money towards an upcoming RO service to remove excess calcium that was detected by my inferior kit. Enough about kits and sarcasm.
So, now my pink and yellow levels are almost equal upon initial reading. When at first I was getting almost no pink, I worried and ran off to Costco for a bunch of bleach. I avoided setting the SWG to "super chlorinate" because I didn't want to stress the device. I normally run it somewhere between 45 and 65 percent. I never used the bleach and now without explanation my levels are almost equal and in fact a little high.
Questions:
Does a SWG system catch itself up by constantly producing FC such that CC just withers away over time? Ca CC be destroyed only by shocking?
