| soft water |
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 softerer. Pools and spas 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.
