Isocyanuric acid is what is commonly called chlorine stabilizer. The normal levels for isocyanuric acid are 30 to 50 ppm.
Note: When the isocyanuric acid level is too high, chlorine has no affect and the reading remains elevated even if chlorine is added. When the isocyanuric acid level is too low, chlorine evaporates quickly in the sun and a larger dose than usual must be used.
