Maybe a dumb question but I have to ask! All of my numbers seem to be good: ph7.5, ch 325, TA 100, CYA 80, Salt 3200 but my FC is 12.5. I don't understand how my chlorine has risen from 4 to 12.5. I have not increased the SWG percentage or have done anything different, the chlorine has just risen. So the dumb questions are why did it climb so high (seemingly on its own, and what should I do to control it? Should I shorten the pump run time? Thanks for the help, and don't laugh too hard if these are rookie dumb questions
