Review on Total Hardness Water Test Strips 🌊 Kit: Accurate Results in Seconds, 100 Count by Corey Krull

I bought these because my city has hard water issues and I had to buy a new water heater because of the hard water. and my plumber told me my town is notorious for it. I also bought an electronic water softener but wanted to test the water before and after. Well after using a few strips it never showed hard water. What I know for sure is wrong. I just wanted to see the hardness level to compare after installing the softener. So I had to give these one star because they don't work. At least the bottle I received didn't work.
