4. Operating Instructions
Follow these steps for accurate water hardness testing:
- Collect Water Sample: Obtain a fresh water sample from the source you wish to test (e.g., tap, well, softener output) in a clean container.
- Dip the Strip: Immerse one test strip completely into the water sample for 2 seconds. Ensure all test pads on the strip are submerged.
- Remove and Shake: Remove the strip from the water. Gently shake off any excess fluid from the strip.
- Wait: Hold the strip horizontally for 30 seconds to allow the color pads to develop.
- Compare Results: Immediately compare the colors on the test strip to the color chart located on the bottle label. Match each pad to the closest color on the chart to determine the water hardness level.

5. Interpreting Results
The color chart on the bottle provides a range of colors corresponding to different water hardness levels, typically measured in parts per million (ppm) or grains per gallon (gpg). Match the color of the test strip pads to the chart to identify your water's hardness:
- Soft Water: Generally indicated by green or lighter brown shades (e.g., 0-50 ppm / 0-3 gpg).
- Hard Water: Indicated by darker brown or reddish shades (e.g., 120-250 ppm / 7-15 gpg).
- Very Hard Water: Indicated by the darkest red shades (e.g., 425+ ppm / 25+ gpg).
Refer to the specific color chart on your bottle for precise readings and recommended actions based on your water source and needs.

6. Maintenance
Proper storage and handling are essential to ensure the longevity and accuracy of your test strips:
- Keep Cap Tight: Always replace the cap tightly immediately after removing a strip to protect the remaining strips from moisture and air.
- Store in a Cool, Dry Place: Keep the bottle in a cool, dry environment, away from direct sunlight and excessive heat.
- Do Not Remove Desiccant Packet: The desiccant packet inside the bottle helps absorb moisture. Do not remove it.
