Review on 💧 Hydrogen Sulfide Test Strip 0-80 ppm by Trevor Garrett

We are looking to buy a water softener and have found that if you have sulfur, the softener can make the sulfur problem worse. So we got these strips to test our waters. We tested our water and the strips showed no sulphur. Then I took a product that was 73 percent sulfur and mixed it with some water. Nothing yet. I took the sulfur product and rubbed it with a test strip and it still showed nothing. waste of time and money.
