There are 5 types of Chlorine; Sodium hypochlorite, Lithium hypochlorite, Calcium hypochlorite, Dichlor, and Trichlor. The first difference is Sodium, Lithium, and Calcium are un-stabilized Chlorine. Dichlor and Trichlor are stabilized.
Pool Water balancing is not such a complicated exercise. ... A pool that is "balanced" has proper levels of pH, Total Alkalinity, and Calcium Hardness. These are: pH: 7.2-7.8, Total Alkalinity: 80-120 ppm, Calcium Hardness, 180-220 ppm and Cyanuric Acid (Stabilizer): 30-50 ppm.
Calcium hardness must be actively managed—along with pH and total alkalinity—to keep water in proper chemical balance. Current industry standards call for maintainingcalcium hardness in the ideal range of 200–400 ppm in pools and 150–250 ppm in spas.
Most pool experts recommend a pool pH between 7.2 and 7.8. To raise or lower pH, a pool custodian simply adds acids or alkalis into the water. For example, adding sodium carbonate (soda ash) or sodium bicarbonate (baking soda) will generally raise the pH, and adding muriatic acid or sodium bisulfate will lower the pH.
