*If your water supply is 15 grains hard and you drank 3 quarts of softened water you would consume 335 milligrams of sodium. That is equivalent to eating 2-1/2 slices of white bread.

**One large banana, about 9 inches in length, has approximately 600 milligrams of potassium.

2.Iron in water can cause stains on clothing and plumbing fixtures. It can negatively affect the taste of food, drinking water, and other beverages. Iron in water is measured in parts per million (ppm). The total* ppm of iron, and type or types*, is determined by chemical analysis. Four different types of iron in water are:

Ferrous (clear water), Ferric (red water),

Bacterial and organically bound iron,

Colloidal and inorganically bound iron (ferrous or ferric).

*Water may contain one or more of the four types of iron and any combination of these. Total iron is the sum of the contents.

Ferrous (clear water) iron is soluble and dissolves in water. This water softener will remove moderate amounts of this type of iron (see specifications). Ferrous (clear water) iron is usually detected by taking a sample of water in a clear bottle or glass. Immediately after taking, the sample is clear. As the water sample stands, it gradually clouds and turns slightly yellow or brown as air oxidizes the iron. This usually occurs in 15 to 30 minutes.

When using the softener to remove Ferrous (clear water) iron, add 5 grains to the hardness setting for every 1 ppm of Ferrous (clear water) iron.
