If you have hard water, you may wonder how hard it is. Measuring water hardness using a water harness scale helps you determine the type of softener you need.
How is water hardness measured? Water hardness is measured in "grains" per gallon, in milligrams of calcium (Ca) per liter, or water hardness may be expressed in ppm - parts per million, and also in German Degrees of Hardness (dH) [which we drop here as this is for fish tanks]. You...
Water hardness isn’t measured in daylights, in sunsets, in midnights, or cups of coffee. No, water hardness is most often measured in parts per million (ppm) or grains per gallon (gpg). But let’s not jump ahead! First, a refresher on hard water and what it can mean for your home...
As discussed in the Water Softeners Buying Guide, hardness of water is measured by grains per gallon (GPG) or parts per million (PPM) of dissolved hardness minerals. Water with less than 3.5 GPG is considered relatively soft; water with more than 10.5 GPG is very hard. Where water is ver...

Enter the water hardness value, in parts per million, into the calculator. Double-check the entry to ensure that it is accurate. Divide the ppm hardness value by 17.1, the conversion factor for ppm to gpg. The result is the water hardness expressed in grains per gallon. For example, say...
Glucanase - An enzyme that act on beta glucans, a type of gum found in the endosperm of unmalted barley, oatmeal, and wheat. Grist - The term for crushed malt before mashing. Hardness - The hardness of water is equal to the concentration of dissolved calcium and magnesium ions. Usually ...
Water hardness is measured in grains per gallon (GPG) or milligrams per liter (mg/l, equivalent to parts per million, or ppm). Water up to 1 GPG (or 17.1 mg/l) is considered soft, and water from 60 to 120 GPG is considered moderately hard. A water softener’s effectiveness depends ...

Pool Shock: Calcium hypochlorite (chlorine) has a very high pH level, so, if you’ve shocked your pool with this inorganic compound, pH levels can spike and the calcium hardness level can increase, causing the water to appear cloudy. Accidentally Dosing With A pH Increaser: It could be ...
