Pawfly Hardness Test Kit - 100 Strips for Drinking, Tap, Well, Pool & Spa Water - Quick & Accurate Calcium & Magnesium Test (0-425 PPM)

Very good value and accuracy, easy to read results in seconds. My water is very hard, so I will be buying a water softener kit

Excellent tool for quickly and accurately testing water hardness. The kit comes with 100 strips, making it a great value for the price. The instructions are clear, and the color chart is easy to read, providing precise results in seconds. I’ve used it for drinking water and my aquarium, and it works perfectly for both. Highly recommend for anyone who needs a reliable and simple way to test water hardness

Use regularly very accurate

Not really sure if these things work or not. It says my water is on the soft side of hard but a professional tester says it's very hard water.

Seems to work, no idea if accurate or not for that can't really go 5 stars but I really like that it comes in a smaller package.

Exactly as it's described.

Purchased these in May 2025. By August, the strips no longer work. I kept them sealed in their own pouch and then sealed in a baggie and stored them in a cool, dry location. So, less than three months and about 10 strips later, the remaining test strips won't register the water's hardness. Regardless of what water is used, they do not change color to register the hardness. I'm going back to the WaterWorks brands. They are 3x the price, but they last. You get what you pay for.

It’s easy to use and gives quick, accurate results. I appreciate knowing the hardness level of my water, which helps me maintain my filter effectively. A must-have for anyone using a water pitcher
