The calcium portion of total hardness expressed as calcium carbonate. Typically 65-75% of total hardness. Low calcium hardness can cause damage to pool surface and components.
Most of the hardness of your water supply is dissolved Calcium salts due to the water having arisen in Chalk or Limestone areas. Magnesium salts also tend to be grouped with Calcium in this description. Some hardness is good for your pool otherwise Calcium from sources such as tile grout will be dissolved. Conversely, too much causes scaling problems.
The calcium content of the water. Calcium hardness is sometimes confused with the terms water hardness and total hardness. Too little calcium hardness and the water is corrosive. Too much calcium hardness and the water is scale forming. One of the basic water tests necessary to determine water balance. Minimum level 150 ppm. Ideal range 200-400 ppm.
a measure of the amount of calcium dissolved in water and expressed in ppm or mg/l as calcium carbonate. The standard measure is 200-400 ppm. (N)
The amount of dissolved calcium in pool water. This should be approximately 200 ppm to 400 ppm, depending on pool finish. Higher hardness levels can cause cloudy water and scale. Lower levels can harm the pool and its equipment.
a measure of the level of calcium salts in the water. Helps determine how scaling or corrosive the water is. Especially important to monitor in pools with a plaster finish.
a measurement of the dissolved calcium content of the water. Can be tested by various methods and is reported as PPM of calcium carbonate. Proper pool or spa water balance usually requires that the calcium hardness of soft water be raised to 150-200 PPM. Higher levels can lead to scaling or cloudy water problems and may require chemical treatment.
The amount of dissolved calcium in water. Low levels of calcium hardness will promote deterioration in the pool surfaces and equipment. High levels will promote scale formation.
The amount of dissolved calcium in swimming pool water. High levels can give rise to scale and cloudy water. Low levels can cause corrosion of metal surfaces of pool equipment.
A measure of the amount of Calcium and Magnesium in water measured in ppm. High levels can cause scale buildup. Low levels can cause etching and equipment corrosion.
A measure of the amount of calcium dissolved in water. Water with low hardness can lead to corrosion of metal parts. Total Hardness Test Kits are available for checking hardness levels ( AquaChek Gold Select).
The quantity of calcium dissolved in water, may promote scale or corrosion.
The amount of dissolved calcium in pool water. Should be approximately 150 175 ppm for vinyl-lined pools, 240 300 ppm for concrete or plaster pools. High hardness can cause cloudy water and scale. Lower levels can damage pool surface and equipment.
(Abbr. CH) The amount of dissolved calcium in the water. High hardness levels cause cloudy water and scale formation. Low levels are harmful to pool and equipment.
The calcium content of water. If too high scale formation occurs, if too low water becomes corrosive. Best levels are commonly between 200-400 ppm.
The amount of dissolved calcium in water (ideal range for PristineBlue® is 300 ppm or lower).
A measurement of calcium dissolved in the pool. The level should be maintained at 200 ppm or more, which helps protect pool surfaces and equipment.
titration test is used to determine levels of the mineral calcium dissolved in the pool water.
the amount of dissolved calcium present in pool & spa water. Low levels of calcium hardness can and do promote corrosion and deterioration of pool surfaces, including vinyl liners, and pool and spa equipment. High levels promote the formation of scale, clogging pipes & scaling pool surfaces. (Ideal ranges: Vinyl Pools 175 - 225 ppm; Concrete / plaster finish Pools 200 - 300 ppm).
The amount of calcium and magnesium in pool and spa water. The ideal range is from 200 to 400 ppm in both pools and spas.
A measure of the level of calcium salts in the water. Helps determine how scaling or corrosive the water is. It is especially important to monitor calcium hardness for possible build-up on heater elements.
The calcium content of the water. If the calcium hardness level is too low, the water may be corrosive. If the calcium hardness level is too high, the water may have a tendency to form scale.
The amount of dissolved calcium in the spa water. This should be approximately 150-220 parts per million (ppm). High levels of calcium can cause cloudy water and scaling. Low levels can cause harm to the spa equipment.
The total amount of dissolved calcium in your pool. The correct level of Calcium Hardness will prevent corrosion and scaling of your pool surface in concrete and fibreglass pools.
A term used to describe the amount of dissolved calcium in your pool water. Ideal calcium hardness levels are between 100 and 500 ppm (parts per million).
A measure of the amount of dissolved calcium in the water. Recommended range is from 200 - 1,000 ppm.
