Even if your water appears to be clear at first you might see orange water once exposed to the air and some staining on your sinks may appear. This is caused from iron or magnesium and the longer it sits without being cleaned the stronger the stain becomes. Hard water can etch glass and crystal.
The easiest and safest way to eradicate the problem is to purchase a water softener or water purification system. A water softener will take care of the scale, but the colored water means you have iron in your water. You will need a specific unit depending if you have city or well water. Ask your water technician during your free water test which unit will take care of all your water problems.
