I know I have hard water, 180ppm. My plumber checked it and gave me a number like 11 GPG (same). BUT I also know that with all the rain we've had, the test results can change. Fingers crossed I received this kit to re-test. The results were a bit strange: a 180 square turned out to be 2 shades! I read the darker shade as 180 and ignored the lighter one. I don't know if the 2 shades mean that the hardness is a little less than 180 or if it's just a coincidence. I think it's close enough. It's still hard water that needs help. ;) I'm trying to decide what to do with hard water. FYI for those with hard water: I've had EasyWater for 5 years now. The first 2 1/2 years "seemed" to work, but then scales started to accumulate. My device warranty (1000) was ONLY 3 years, ie Apparently the device "on time" started to fail. I called the company before the deadline and was told it could just be an environmental condition that could pass. Well it never went away and now I have slime, scale and crystals on the edges of my relatively new faucets. This week, 2013, Easywater told me to "wipe the ends of the faucet after use" (that's serious, yes!) and "buy a salt softener" (!). of course), but they CONTROL them! So if this one stays here, be thankful to Revane and be warned.
