🔧 Troubleshooting

The water hardness test strips are giving inconsistent results.

Ensure that the test strips are not expired and are stored in a cool, dry place. Make sure to follow the instructions carefully, including the timing for reading the results. If the issue persists, consider trying a different brand of test strips.

The DIY bottle test is not producing clear results.
