MEASURE WATER HARDNESS - How is Water Hardness Measured?

Water hardness is measured in "grains" per gallon, in milligrams of calcium (Ca) per liter, or parts per million, and German Degrees of Hardness (dH) [which we drop here as this is for fish tanks]. You can take a water sample to a water test lab to have its hardness measures.

Use this simple soap test to measure the grains of hardness of your water supply

But water hardness can be easily measured using a simple soap test kit that will measure in "grains of hardness" (a little bottle with a line marked on it which you fill to the line with water, add a drop of soap, and shake to look for suds. More drops of soap - more degrees of hardness).

I bought my water hardness kit at Sears where water softeners were sold. Or the hardness of your water may be measured at no charge if you ask the local water treatment company to take a look.

Beware, they won't fib about the hardness level, at least not many companies, but they do want to sell you equipment.
