Calcium Chloride In Pool Water

How to add calcium chloride to a pool step 1.

Calcium chloride in pool water.

Having the calcium hardness out of range can lead to problems with water quality and equipment damage. Test your pool water and your fill water for calcium hardness. Low calcium levels in a plaster pool will cause the water to draw calcium. Calcium hardness rises over time as water is evaporated from the pool and fresh water is used to top the pool up.

All this affects the quality of the water thus the need for constant cleaning and filtration. The fresh water will contain some dissolved calcium which remains in the pool when more water evaporates. Recommended range for pools is between 200 400 ppm. So the ch reading rises inexorably over the years.

Calcium chloride for pools the environment influences pool water from leaves swirling down to the swimmers to airborne dust particles. How can you add the vital chemical calcium chloride to your swimming pool safely and efficiently. Calcium hardness should be tested regularly using test strips or reagents. Soft water low calcium levels can cause plaster or concrete pool walls to lose their calcium to the pool water and can cause vinyl pools to lose their elasticity.

Data for com onent. Dip the bucket into the pool until it is about 3 4ths full of water. Slowly pour the measured amount of calcium. A dissolved calcium level that is too high hard water can be damaging to a pool but a low calcium level soft water can also cause problems.

In addition the water should have a proper balance of acidity alkalinity and calcium hardness. Why is it so important. Although soft water is desirable in everyday home use calcium hardness is necessary in pool water. Newly filled pools in areas with soft water or pools filled with rainwater may have a low ch but this can be remedied inexpensively by adding calcium chloride flakes.

Calcium chloride material is practically non toxic to aquatic organisms on an acute basis lc50 ec50 100 mg l in the most sensitive species tested.
