Just to make sure I am following you, If I add one pound of cyanuric acid into a 7,000 gallon pool, it would raise my CYA as followed:

120,000/7,000 = 17.14, so my CYA level would raise 17.14 ppm ????






Also, confused on the bleach, so 1 gallon of 6% bleach will raise a 12k pool 10 ppm ???

120,000/x = 10ppm so.... x = 12,000 gallons.

You said that 1 lb of cyanuric acid = 1ppm, how much does a gallon or quart weigh?
One pound of CYA in a 7K gallon pool will raise your CYA by just over 17 ppm, so you've got that one right. However, 1 gallon of 6% bleach in 12K gallons will raise your FC by 5 ppm. One gallon of 6% bleach in a 7K gallon pool will raise your chlorine by approx. 8.5 ppm.

One gallon of water weighs approx. 8.4 pounds....
