Hardness reducer is phosphate base chemical. It maintain the phosphate level in boiler water drum. It react with silica & setteled down silica to bottom of the drum which we can remove by the blowdown.The reason you balance alkalinity, pH, then calcium hardness is that adjusting alkalinity often affects pH. Adjusting both alkalinity and pH often affects your calcium hardness, as adding sodium bicarbonate (baking soda) and sodium carbonate (soda ash) can increase the hardness of your swimming pool water.Too high: Add plain ph'd water to the reservoir and test. Repeat until your reservoir reaches a safe fill point, or the ppm is in the correct range. If the ppm is still too high, you can wait for the plant to lower the water levels, or you can change the reservoir water altogether.

Hardness Reducer

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. Chlorine levels should remain constant in the 1-3 ppm range.According to the BIS, the ideal TDS for drinking water is below 300mg/L and the max permissible limit is 600mg/L. It is recommended that people with kidney problem should drink pure water having TDS level below 100 mg/L for better recovery.
