JP,
I noticed that yesterday you had 1ppm CC and you didn't report it today. Do you have any? You may still be fighting something in your water and 14ppm FC is well below your shock value of 20ppm FC for 60 CYA. If this were my pool, I'd add 3 gallons of bleach to get the FC over 20 and keep it there 'til the CC is gone and the FC drops less than 1 ppm overnight. And keep the filter running.
