Have been doing your method since last year, got myself that nice $100 test kit from taylor too.
Levels at the moment are
Ive been running the filter (sand) nonstop with the chlorine level this high for about a week now and its still cloudy with a tint of green. I try vacuuming (not to waste) but it only gets the stuff off the floor and then kicks up the rest to make it more cloudy.
I did use pucks in the beginning of the season to help raise the CYA (I know I shouldn't have).
Also im not sure if this is relevant but the top part of the filter, the female housing for the plastic little screw, has cracked and now constantly lets air out. I sealed I with duct tape to keep the pressure up (which it stays at 15-20 no problem) but I do hear hissing.
Not sure what to do except keep bleaching and filtering.
Also how often should I be backwashing? The pressure doesn't build up beyond 20 to give me a red flag to backwash, although every time I do it is very thick green.
