Calcium hardness in vinyl swimming pools.
If calcium hardness goes above 400 ppm you will likely see a white flaky crust on the liner and pool equipment.
If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm.
Calcium is always present in your pool.
If your pool has a vinyl or fiberglass liner the calcium hardness level should be between 175 parts per million ppm and 225 ppm.
Dip the test strip dip the calcium hardness test strip into the pool water.
Excessive calcium in a pool is typically the result of an imbalance in your pool water and it can result in white scaly buildup.
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.
The ideal reading for calcium hardness in pool water is about 200 to 400 parts per million.
But what it depends on isn t that difficult.
Low calcium levels in a plaster pool will cause the water to draw calcium directly from the plaster causing it to pit become rough and eventually crumble.
If a vinyl liner s calcium level is too low this soft water situation could lead to foaming and other water problems and can harm the vinyl.
These are symptoms of swimming pool water that is unbalanced.
Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.
Hardness is the measure of how much calcium or calcium carbonate is present in your swimming pool water.
The recommended range is 150 400 ppm parts per million with an often cited stricter range of 200 400 ppm.
Truth be known vinyl liner and fiberglass pools are likely to decline faster in a low calcium environment.
Although soft water is desirable in everyday home use calcium hardness is necessary in pool water.
What is calcium hardness.
If you re faced with a re plastering job on your pool you ll realize.
Here s your favorite answer.
For vinyl pools calcium should be between 150 250 ppm.
High calcium is rarely a problem if other lsi factors are adjusted properly 500ppm calcium hardness is easily managed without scale formation.
Fortunately calcium hardness changes rather slowly so a once a month testing and adjustment should be all you need.
