  • Gives true reading
Size: 1-pack
I had a different brand of strips that I didn’t feel I could trust. These are easy to use and I know they give a true reading

  • Takes the guess work out of setting your softener
Size: 1-pack
These strips work perfectly for setting your water softener correctly. I highly recommend them. Simply measure your water hardness at an exterior hose spigot and set your softener to whatever that ends up reading. Mine measured at 7. After your softener has been running for awhile you can take a measurement from inside the house to see if it’s working correctly. Inside the house measured at 0 so I know my softener is working. Important: Do not measure at the kitchen sink. Many homes do not soften the cold water in the kitchen this will lead to incorrect readings and you will end up thinking your softener isn’t working correctly. Test at a bathroom faucet. That’s it, quick and easy. ... show more

  • Compared softened versus hard water source at my house - The strips worked very well.
Size: 1-pack
The water in my township is hard. It measures 13.5. I soften the water inside my house and the bottom strip that I used to test that shows a reading of zero. I do not soften the water leading to my exterior water faucets and the top strip that I used to test that water shows that the water is very hard. No doubt, the strips provide an accurate reading. ... show more

  • Caution... These worked great at first, but after several months..
Size: 1-pack
Worked great at first, but several months later gave me false readings making me believe my water softener had issues. After spending 2 weeks troubleshooting/ emptying it 2 times, I found the test strips were indeed at fault. Cost me a lot of $$, stress and time.

  • Didn't give any reading.
Size: 1-pack
Uncapped bottle and noticed inner seal was broken. Tried three strips on three different sample on my well water and had no color change at all. Would not recommend.
