My CC went up from 0 on Sunday to 0.2 tonight. My FC dropped from 8 to 6.4 overnight, but we had a high of 86 and people have been swimming regularly. Also the pool is in direct sun until around 6. I'm not worried, just wondering if that sounds normal or is that the canary in the mine. I guess my real question is, when you see an increase can you just increase the FC double the CC to combat it early rather than wait for a SLAM later.
