With a CYA reading of 180, your shock level will be 25ppm. Since your pool is still green, go ahead and add enough bleach to get back to 25. In your pool, each quart of 8.25% bleach will add about 1ppm of chlorine and each of the 121-oz bottles will add about 3.5ppm. Use those as a reference to help you figure out how much bleach to add.
While you are working to clear this up, test your pool each evening after the sun is off the pool. Add enough bleach to take the chlorine level back up to 25ppm. Run your pump 24/7 right now and backwash the filter as needed. Also, brush the pool while the chlorine is high.
Continue to keep your pool at shock level until two conditions are met:
1) You can go from sundown one evening to within an hour of sunrise the next morning without losing more than 1ppm of chlorine. AND --
2) You have no more than 0.5ppm of CC.
Then, you can let the chlorine drift down but always keep it between 8-15ppm after that or else you'll get algae again. (Did you look at the chart that Kevin linked for you in post #6 above?) Only use bleach from now. No trichlor pucks or dichlor shock powder. Both contain CYA and you certainly don't want any more in there!
Your pH is ok at 7.2 but keep an eye on it and if it drops any further, use some Borax to bump it back up. (Never let it drop below 7.0.)
Keep us posted how your progress is going.
