Calcium Hardness Level

It is important to know the calcium hardness level in order to determine the proper model to choose.

Municipal water – you can easily obtain the calcium hardness level by contacting your city or country water department or visiting their website. Standard calcium hardness test kits are available at all pool supply stores that will give you an accurate reading. You can have them perform this very quick and simple test for you.

Using our USA hard water map – you can use this map as a guideline to the calcium hardness level in your area.

Well water – is usually harder than municipal water and the water should be tested using the calcium hardness test kit or tested at a pool supply store. If you are unable to do that, we recommend purchasing the SB-Elite or the SB-MAX PRO.
