I used them to check the hardness of my tap water and my softener system β€” both readings were accurate and easy to interpret thanks to the color chart. The included eBook is a nice touch, explaining water hardness and maintenance tips in simple terms. With 150 strips, it’s an excellent value for ongoing testing. Review: Quick and easy to use, but check within 30 seconds! - I had a whole-home HALO5 filtration system installed recently and felt like our water was much harder than when we only had a water softener. Bought a box of these to check for hardness. Easy to use and the hardness registers almost immediately. IF YOU HAVE HARD WATER, you need to check them within 30 seconds or so, otherwise the color of the test changes (see picture). When the filtration guy came out to check the HALO5 system, he read the strip immediately, and after a few minutes and said it wasn't that hard. I asked him to use another strip and that they were supposed to be read within 30 seconds. Within just a few minutes, it starts showing the original color of the test strip (which is green for soft). You can still see some of the rust color, but the green definitely shows through. I tried this with distilled (soft) water and the test color showed very soft. After an hour it was the same color just a bit lighter. BE SURE TO READ THE STRIP WITHIN 30 SECONDS FOR ACCURACY! ## Features - CHECK WATER HARDNESS: This handy water hardness test kit allows you to test the hardness of all water sources, from home faucets and taps, to well water, water softeners, dishwashers, showers, aquariums, and many more - MULTIPLE USES: The right levels of water hardness can make a huge difference in the softness of your laundry.
