The change in water by Acqua 1 is not only indicated by oxygen bubbles and crystalline changes but also by a change in taste.

You can easily test the change in taste with lemon juice.

1. Take two glasses.
2. Pour untreated tap water into one glass and in the other glass pour water treated using Acqua 1 as described in the instructions for use.
3. Pour 20 drops of lemon juice in the two glasses. Then you will taste the difference. The water treated with Acqua 1 tastes more pleasant and not sour.
