The fresh water will contain some dissolved calcium which remains in the pool when more water evaporates.
Calcium chloride in pool water.
Why is it so important.
Calcium hardness rises over time as water is evaporated from the pool and fresh water is used to top the pool up.
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.
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.
Having the calcium hardness out of range can lead to problems with water quality and equipment damage.
How can you add the vital chemical calcium chloride to your swimming pool safely and efficiently.
Although soft water is desirable in everyday home use calcium hardness is necessary in pool water.
In addition the water should have a proper balance of acidity alkalinity and calcium hardness.
Calcium chloride for pools the environment influences pool water from leaves swirling down to the swimmers to airborne dust particles.
The orenda app will tell you.
Test your pool water and your fill water for calcium hardness.
With sufficient levels of calcium dissolved the aggressive nature of water is tamed and will help prevent the leaching out of certain substances in pool equipment.
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.
A chlorine free water treatment for pools.
Calcium hardness should be tested regularly using test strips or reagents.
Slowly pour the measured amount of calcium.
So the ch reading rises inexorably over the years.
All this affects the quality of the water thus the need for constant cleaning and filtration.
How to add calcium chloride to a pool step 1.
Dip the bucket into the pool until it is about 3 4ths full of water.
Recommended range for pools is between 200 400 ppm.
