Update....after an hour or two in daylight, small pockets of algae we're starting on the floor of the pool.

Yesterday, before shocking, my FC was 3.5 and CC was 0. I added 2 gal of bleach, which took my fc to about 17 then added polyquat. This morning my fc was 11 and cc was .5. I added 12c of bleach, estimating that would take my fc above 15. Should I be doing anything else?
