Was out of town when the valve was serviced by local pool guy. Turns out he told my wife not to add any bleach to the pool as we had too much, I think around 14(was not too much for shock level according to CYA of 60). She hadn't added any since Thursday.. I tested yesterday and the FC was at 0 so I added enough to hit 24 (CYA 60). The pool has tinted back to a slightly greener green than it was yesterday. It actually had a blue tint yesterday and was looking better than today. Just wondering how adding the bleach could make the pool appear more green than when it has FC of 0? Thanks again for all the help.
