Calcium Hardness In Pool Is Low

When it is too soft equipment.

Calcium hardness in pool is low.

Hard water can cause lime to be precipitated. Here s your favorite answer. These are symptoms of swimming pool water that is unbalanced. Current industry standards call for maintaining calcium hardness in the ideal range of 200 400 ppm in pools and 150 250 ppm in spas.

Dip the test strip dip the calcium hardness test strip into the pool water. The role of calcium hardness in water balance. If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm. Recommended range for pools is between 200 400 ppm.

In addition to phand total alkalinity calcium hardness must be kept in balance so that your pool water does not become too corrosiveor end up scalingthe surface of your pool. Water with a calcium hardness above 300 ppm mg l is described as hard water. Soft water can draw lime out of tile grouting and the concrete of cast pools which can lead to disintegration. Although soft water is desirable in everyday home use calcium hardness is necessary in pool water.

Hardness on the other hand is a measure of the calcium and magnesium in the water. Rain or melted snowthat finds its way into your pool can reduce the calcium hardness as water from rain and snow is naturally soft water and lacks calciumor magnesiumdissolved in it. Calcium hardness should be tested regularly using test strips or reagents. Water with a calcium hardness of less than 100 ppm mg l is described as soft water.

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. Calcium hardness must be actively managed along with ph and total alkalinity to keep water in proper chemical balance. If you re faced with a re plastering job on your pool you ll realize. The most common cause of low calcium hardness is the introduction of water that has fewer minerals dissolved in it.

Swimming pool calcium hardness must be managed to maintain balanced pool water. The ideal reading for calcium hardness in pool water is about 200 to 400 parts per million. The recommended range is 150 400 ppm parts per million with an often cited stricter range of 200 400 ppm. Having the calcium hardness out of range can lead to problems with water quality and equipment damage.

If your pool has a vinyl or fiberglass liner the calcium hardness level should be between 175 parts per million ppm and 225 ppm. Fortunately calcium hardness changes rather slowly so a once a month testing and adjustment should be all you need.
