Why customers choose Cera Garden
Discover a practical way to understand and monitor water hardness with the JNW Direct Water Hardness Test Kit. This easy-to-use kit includes 150 test strips and a helpful eBook, designed to help you track hardness over time and make informed decisions about laundry, appliances, and filtration. The color chart provides clear, visual feedback, making readings simple even for first-time users.
What makes this kit useful? It covers multiple common sources, including home faucets, well water, water softeners, dishwashers, showers, and aquariums. By checking hardness at different points in your household, you can spot trends and gauge whether your water conditioning systems are performing as expected. While not a medical product, noting changes in hardness can help you plan maintenance, optimize RO systems, and adjust detergent use where appropriate.
The testing process is straightforward and fast: dip a strip, compare it to the color chart, and record your result. The included eBook enables you to log readings, track progress, and observe how readings shift over weeks or months. With 150 strips, you have ample material to test multiple samples or repeat tests for accuracy.

Note: This kit provides testing data that can inform decisions, but it does not replace professional advice. Use it as a practical tool to understand your water profile and guide maintenance planning.
