RO is probably the best way to go, but you can get around it. You could get a small boy water filter and take the chlorine and some of the sediments out before use, this is my next step before RO Water is described as "hard" when it contains high levels of dissolved minerals - primarily calcium and magnesium. The hardness of your water varies depending on which water plant serves the area. The table on this page shows the hardness of the water by zip code for JEA's service territory. The greater the amount of dissolved minerals in the water, the harder it is.

If you do not have any dissolved iron in your water, just use your water hardness and the hardness buffer of 20% of your water hardness based on the age of your water softener. Not all water softeners will need to be set higher just because they are more than 10 years old, but water softener resin does lose its efficiency as it gets older so the small buffer adjustment may be necessary.

2021-02-16 · One grain per gallon (gpg) is equivalent to 17.14 parts per million (ppm). A water hardness of 0 to 3 gpg is soft water, 3 to 7 gpg is moderately hard and 7 to 11 gpg is considered hard. the hardness level of your water. Less expensive home tests also are available from local hardware or home supply stores. The following classifications are used to measure hardness in water: soft 0 - 17.1 parts per million (ppm); slightly hard 17.1 – 60 ppm; moderately hard 60 - 120 ppm; hard 120 - 180 ppm; and very hard 180 or more ppm. The total sum of these salts determines the actual water hardness.
