How Do You Conduct A Calcium Hardness Test?
Maintaining a proper chemical balance in your swimming pool or hot tub is essential. Possessing knowledge about how to test calcium hardness (or the amount of calcium in the water) will be helpful for this purpose. Too much calcium can lead to a scaly buildup on the surface of the water, clogged plumbing, and eye irritation. With too little calcium you may see scarring on the pool’s surface and corrosion of the pool equipment, such as piping and the pump. The proper level is above 200 parts per million (ppm) and below 400 ppm. Take a water sample from at least 12 inches below the surface. Treat with a calcium buffer and then dye. The water should be a red color. Add hardness reagent one drop at a time until the red turns blue. Keep count of the number of drops it takes. Multiply the number of drops by the constant provided in the water-testing kit. This number gives you the calcium harness level. Add more calcium chloride if results fall below 200 ppm. Remove some of the water if the r
