The Hard Water Test Kit will show you how hard your water is in grains or ppm. It’s simple to use and performs approximately 50-100 tests. It’s a tool we created to help you determine when your WaterStick water softener needs to be regenerated but it can also be used if you just want to know the hardness of your tap water.
