How do you test water quality at home?
Water quality test strips
- Fill a test container with a water sample, dip a test strip in, swirl the container, and wait a few minutes with the test strip resting in the water sample.

| Concentration of hardness minerals in grains per gallon (GPG) | Hardness Level |
|---|---|
| 3.5 to 7.5 | moderately hard |
| 7.5 ti 10.5* | hard |
| 10.5 and above | very hard |
What is the Colour for water?
