Calcium Reduction Composition and Method |
| abstract |
A formula and method for reducing water hardness includes the combination of a sulfate donor, salt of phosphoric acid, and salt of sulfamic acid. Preferred formulas include effective amounts of sodium bisulfate, sodium hexametaphosphate, and sulfamic acid. In a swimming pool, preferred formulas are effective in reducing calcium to under 200 ppm within a two day period. In addition, preferred formulas provide ongoing effectiveness in suppressing scaling, staining and cloudy water. |
