water that is free of calcium or magnesium salts. Compare hard water
Any water which contains less than 1.0 gpg (17.1 mh/1) of hardness minerals, expressed as calcium carbonate.
water with dissolved solids which are less than 100 ppm.
is water that is low in calcium and magnesium hardness. Such water can prove to be corrosive to masonry surfaces and underwater metal parts. The calcium hardness level can be raised, to the optimum range of 150-200 PPM, by the addition of appropriate amounts of a calcium hardness increaser (calcium chloride). Vinyl pools can be maintained at a lower level: 80-200 PPM.
Water with a low content of dissolved minerals and solids. Usually Acidic.
Water that contains less than 100 ppm of calcium and magnesium.
Water that is sufficiently free of calcium and magnesium salts so that no curd (oily matter) will form when soap is used. Generally, soft water is a relative term.
water that is not hard (does not contain salts that interfere with the formation of lather with soap)
Water that does not contain those minerals that prevent free lathering when soap is added (see Hard Water).
Any water that does not contain large concentrations of the dissolved minerals calcium or magnesium.
Water that does not contain large amounts of dissolved minerals such as salts containing calcium or magnesium.
Water with relatively low concentrations of minerals.
Water with a low concentration of dissolved salts.
Water that is free of magnesium or calcium salts.
Any water that is not "hard," i.e., does not contain a significant amount of dissolved minerals such as salts containing calcium or magnesium.
water which contains more sodium ions than hard water. Soft water makes soaps form a lather (bubbles) better than hard water. Soft water does not make your kettle fur up.
Water that contains low levels of dissolved minerals, such as salts, calcium, or magnesium.
Soft water is that which will readily form a lather with soap because there are no calcium or magnesium salts present.
Water that contains low concentrations of metal ions such as calcium and magnesium. This type of water does not precipitate soaps and detergents. Compare to Hard Water.
Water with low calcium and magnesium levels with hardness levels below 100ppm, pools should be maintained at 150-200ppm. Calcium chloride increases water hardness.
Water that contains little or no calcium or magnesium salts but is highly acidic.
Water containing less than 20mg/l of hardness as measured in CaCO3 (see explanation also of Hard Water).
Water containing low concentrations of calcium and magnesium. Soft water lakes are common on the Precambrian Shield in northern Saskatchewan, Manitoba, Ontario and Quebec; they are not common in Alberta. See also hard water.
Conditioning of water due to lack of dissolved salts. see also acidic
Water that has a low concentration of dissolved minerals (primarily calcium).
Water that contains low concentrations of hardness-causing minerals, such as calcium and magnesium.
Water that has a very low calcium and magnesium content (water hardness) – usually means less than 100 ppm or 6 grains. Also, water that has gone through a water softener. Pools and spa should never be filled with soft water from a softener. Water with less than 100 ppm of hardness should be increased to a minimum of 150 to 200 ppm using calcium chloride.
A water quality, characterized by containing very small amounts of dissolved salts.
Water that has low calcium and/or magnesium content. Soap lathers easily in soft water.
A water condition with very small amounts of dissolved salts.
Water which contains little or no calcium or magnesium salts, or water from which scale forming impurities have been removed or reduced.
A water low in calcium and magnesium.
This type of water contains extremely low concentrations of calcium, magnesium, or calcium.
Water that has a low calcium and/or magnesium content. Soft water can result in the etching of the pool's surfaces, and should be increased with calcium chloride.
water free of dissolved calcium and magnesium (hardness minerals); also referred to as conditioned water
Any water which naturally contains less than 1.0 grain per gallon (17.1 mg/L or ppm) of total hardness expressed as calcium carbonate equivalent.
Water low in calcium and magnesium mineral content.
Water without significant hardness, that is, low ( 60 mg/l) in concentration of magnesium or calcium salts.
Water that has very few minerals, which makes it more suitable for washing because there are not calcium deposits or soap scum left on the surfaces.
Any water which contains less than 1.0 gpg (17.1 mg/l) of hardness minerals, expressed as calcium carbonate
Soft water is the term used to describe types of water that contain few or no calcium or magnesium ions. The term is relative to hard water, which does contain significant amounts of such ions.
