My FC has been running right around 5 with my filter and SWG running for 8 hours per night at 40%. All of a sudden after this weekend my FC is at 10 and I can't get it down. I finally turned my SWG off and will leave it off until I get it down. Any idea why the chlorine level would rise with no other changes? Only thing I did this weekend is shock the pool with a non-chlorine shock (Fresh 'n Clear from Leslies) and add MA to lower the Ph from 7.8. Water looks great but you can smell chlorine when you walk into the backyard.
