In 33K gallons of water, 11 gallons of 6% bleach should give you approx. 20 ppm of Chlorine, which is where you need to be to achieve "shock" level for a CYA of 60. After you add that initial dose,and get to 20 ppm, you need to test and add more chlorine as often as possible to maintain that 20 ppm level--that means in a pool your size, each 1/2 gallon of bleach will raise your FC by 1 ppm, so when you retest, add whatever amount of bleach you need to get back over 20 ppm. You need to hold it at or above the 20 ppm mark until it clears up and you are not losing more than 1 ppm of chlorine overnight. This is a process, not a one-time thing. The more consistent you are about maintaining the 20 ppm, the faster the pool will clear up. And...if you're planning to have a pool party this weekend, you're going to need to be very consistent about it if you want to be able to use the pool. Keep your pump running 24/7 while you're doing this, cleaning your filter as the pressure indicates, and brush the pool at least once a day.

Good luck!!
