To calculate how much calcium chloride your swimming pool requires to increase the calcium hardness, choose the increase you want and enter the volume of your swimming pool. Flexibility: Raises calcium hardness maximum levels to 2500ppm. Adding stabiliser (cyanuric acid). Pre-diluted chlorine may now be added to achieve 1.5 to 3 ppm. Typically you fill a small bottle with water up to the mark on the side, then add a chemical from the kit drop by drop. The accumulation of scale caused by high levels of calcium hardness can be detrimental to hot tub components like the jet pumps and heater, as well as to the electrodes within the ACE system. Hi Richard, a salt system like IntelliChlor will create the chlorine automatically, from pool salt added to the pool, but will not affect pH, alkalinity, calcium hardness or cyanuric acid levels, and won’t monitor those levels, so you will still need to test and adjust occassionally. Flexibility: Raises calcium hardness maximum levels to 2500ppm. Whichever mineral method you decide to use, whether skimmer basket, floating dispenser, or inline system, always make sure to follow the manufacturer’s guidelines when using their product.
