So, each evening, when you test your chlorine, you'll want to add enough bleach to take the chlorine level up to 25ppm. In case you have forgotten from a post earlier in this thread, in your pool, each of the 121-oz jugs of 8.25% bleach will add about 3.5ppm of chlorine. Use that as a reference to figure out how much bleach to add each evening to get back to 25ppm. You'll want to continue keeping the chlorine level at 25ppm by using bleach until you meet 3 criteria:

1) You lose no more than 1ppm of FC from sundown to within one hour of sunrise the next morning.
2) You have no higher than 0.5ppm of CC
3) Your water is clear

At that point, keep the chlorine at 25ppm for one additional day and then you can let it drift down and keep it between 8-15 ALL the time. I would not advise using any more stabilized forms of chlorine in your pool like trichlor tabs or dichlor powder as they will both make your CYA continue to climb and yours is already really high.

Also, remember that when you test pH, you will get an invalid result if your chlorine is over 10ppm with a Taylor kit. (Over 5ppm with other kits.) So, dilute your sample -- half pool water and half distilled water and run the pH test with that mixture if your chlorine level is over 10ppm.

When you do the chlorine test, use the 10mL sample instead of the 25mL one and it will make your reagents last longer. You'll multiply the number of drops by 0.5 instead of 0.2. Also, if one scoop of the powder turns the water pink when you do the FC test, you don't need to add the second one. That, too, will save on your reagents.

Hope this helps.
