The recommended range is 150 400 ppm parts per million with an often cited stricter range of 200 400 ppm.
Calcium levels in pool water.
In store and online at e z test pool supplies.
The ideal reading for calcium hardness in pool water is about 200 to 400 parts per million.
The optimal calcium level is 200 400 ppm.
A higher ppm causes deposits on the surface and cloudy water.
Prolonged exposure to water high in calcium can cause a total system failure of a swimming pool.
The difference between a pool that is corrosive or not simply relies on a higher calcium hardness level.
Dip the test strip dip the calcium hardness test strip into the pool water.
You don t want your pool water to be too hard or too soft.
And we all thought we were within range.
Calcium hardness control 7lb availability.
The ideal range for calcium hardness in swimming pools is 150 400 ppm parts per million.
If you keep your calcium hardness in the midpoint between those two limits about 275ppm then you should be fine.
In addition to ph and total alkalinity calcium hardness must be kept in balance so that your pool water does not become too corrosive or end up scaling the surface of your pool.
It is remarkably consistent when left alone and when coupled with good lsi management calcium hardness helps water chemistry behave in a more predictable way.
The first thing you ll want to do is remove calcium from pool water.
So check those calcium levels adjust as needed avoid expensive repairs and oh yeah keep swimming.
Swimming pool water high in minerals such as calcium will form scales on the pool walls in the piping and in the filters clogging these systems reducing the flow of water and decreasing the efficiency of the filter.
See your local water professional but generally calcium levels in the range of 200 to 400 ppm that s parts per million is where you want to be.
If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm.
These are symptoms of swimming pool water that is unbalanced.
For this you ll need to partially drain your pool.
Either way you re in trouble.
The calcium range for the best pool water is between 250 and 350 ppm.
Fortunately calcium hardness changes rather slowly so a once a month testing and adjustment should be all you need.
Reduced pool chemical effectiveness.
Good calcium hardness levels can make managing pool chemistry so much easier and cost effective.
Keeping your calcium hardness in the midpoint between the low and high should be your goal.
