Looks like easy water to work with.

Actually, if it were me, I'd go to Sams and get 50# of dichlor. That translates into about 75 ppm of chlorine for your pool . . . and about 60 ppm of stabilizer. That may be higher than you want to go, but the dichlor is easy to use during start up, and won't dissipate instantly like bleach will in a clear water unstabilized pool.

If you are going to use bleach, 60ppm of CYA is a good level to work with. Keep in mind that, at 1 ppm per day, you'll need around 9 gallons of 6% bleach per week for that big pool.

You may want to look at other options. If you have a sand or DE filter, you can use cal hypo without having uncontrolled TA & CH rise . . . if you do it the way I tell you. Or you may want to install a salt system, if your pool components are compatible and if it fits your budget.
