How Do I Really Know if my Salt Free System Works?Lots of companies are selling salt-free water softeners and salt-free conditioners. There are a few tests that you can perform to determine if they are indeed doing what they say.
1. Test to see if the water really is softThis can be done by purchasing a small professional-grade water hardness test kit like this: https://www.uswatersystems.com/hardness-field-analysis-test-kit-2403.html It consists of three (3) simple steps which take about 20 seconds. At the end of the test, you will know if the water is soft or not. If the water is more than 1 grain per gallon (gpg), it is hard water. If you have purchased a salt-free "water softener", I suspect that you will find that your water is hard. No, let me re-phrase that - you will ABSOLUTELY find out it is not soft, but that doesn't mean that it might not prevent scale.
2. Test to see if the water will form scaleThese tests are a little more difficult, but can be accomplished in a few minutes. First, take a spray bottle and add your water to it. Next, spray a slight mist on your bathroom mirror, just so that it is wet. Let it air dry naturally and you will see spots. If those spots wipe off easily without chemicals or scrubbing, then the system is working properly to prevent scale. The next test, also confirms the first one. In this test, you add about an inch of water to the bottom of a pan and boil it dry (don't allow it to over-boil as you may warp the pan). After the pan cools (so that you won't burn yourself), you will see a white residue in the bottom of the pan. If the system is working, you should be able to wipe off the white residue with your finger. If you have to scrub it or use chemicals, it is not working. There are many systems on the market today, but we have determined that the best method for preventing scale without salt is using Filtersorb SP3 Media in our Green Wave Salt Free Conditioners. We have tried all of the other methods and we are most confident with the NAC Process of Filtersorb SP3. Some companies call the process TAC, but we believe the process is virtually the same.
