Sunlove,

In a 7500 gallon pool, each 1 cup of 6% bleach will raise your FC by 1 ppm. Each gallon will raise it by 8 ppm. You can use these as a guide to figure out how much to add. The key is to add enough to get to shock level (dependent on your CYA--see the best guess chlorine chart linked in my sig) and then test and add more as needed to get back up to that level until the pool clears. The more consistent you are about maintaining the shock level, the faster it will happen.
