Getting ready to close here in MD. I shocked and now my FC is at 14, cya is 90, and ph is 7.75. The instructions on the polyquat say to add with FC at 1 to 3ppm, but since the pool is covered and it's cold, that FC is not wanting to drop. I really want to take care of closing the lines this w/e. Would anything really bad happen adding the poly at these chem levels?
