If your pool doesn't have enough CYA, the easy fix is to use Dichlor chlorine.It's 1 1/3 lbs.per 10,000 gallons to shock the pool and raise the CYA 9ppm.ver stabilized pool water is known as a high concentration of Cyanuric Acid (CYA/stabilizer/conditioner) over 80 ppm. The proper range for CYA is 30 - 50ppm. Under stabilized pool water is when you don't have enough CYA. Too low is 20ppm, 10ppm, or obviously 0ppm.
